Exchange 2010/2013/2016: Starting Exchange Services with a simple command
As an Exchange Admin, you might be looking after 1 server or several hundred.
Sometime after a reboot you might notice that some of the services don’t start. It is a daunting task to go manually start them all 1 at a time.
A simple way is to run the following command from an elevated PowerShell Window:
- Get-Service *Exchange* | Start-Service
Some services like the Transport and Unified Messaging Services take a bit longer to start but the window will echo the starting of all services.

Test SQL connectivity remotely easy!
Have you ever been troubleshooting a problem with remote SQL Iproxy MP, remote DB, etc) and wanted to test to see if the local system account (or any account for that matter) could make a remote connection to SQL but you didn’t want to install the SQL tools just to make that test? Seems there is a file type – UDL file – that you can simply create that will bring up a window to allow testing of remote connections to SQL.
Just go anywhere on your system and create an empty text file named anything but instead of txt make sure the extension is UDL. Then, double-click on the file and up pops a SQL connectivity window to allow testing of remote SQL connections.
Install LAMP on CentOS 7
Before we install the LAMP stack, it’s a good idea to run the following command to update repository and software packages.
yum update
Enter the following command to install Apache Web server. The httpd-tools package will install some useful utilities like Apache HTTP server benchmarking tool (ab).
yum install httpd httpd-tools
After it’s installed, we can start Apache with this command:
systemctl start httpd
Enable Apache to auto start at system boot time by running the following command.
systemctl enable httpd
Now check its status.
systemctl status httpd
Check Apache version.
httpd -v ************************************************************** By default, CentOS 8/RHEL 8 forbids public access to port 80. To allow other computers to access the web page, we need to open port 80 in firewalld, the dynamic firewall manager on RHEL/CentOS. Run the following command to open port 80.
firewall-cmd --permanent --zone=public --add-service=http
If you want to enable HTTPS on Apache later, then you also need to open port 443.
firewall-cmd --permanent --zone=public --add-service=https
The --permanent option will make this firewall rule persistent across system reboots. Next, reload the firewall daemon for the change to take effect.
systemctl reload firewalld
Now the Apache web page is accessible publicly.
Finally, we need to make user apache as the owner of web directory. By default it’s owned by the root user.
chown apache:apache /var/www/html -R
**************************************************************
MariaDB is a drop-in replacement for MySQL. It is developed by former members of MySQL team who are concerned that Oracle might turn MySQL into a closed-source product. Enter the following command to install MariaDB on CentOS 8/RHEL 8.
yum install mariadb-server mariadb -y
After it’s installed, we need to start it.
systemctl start mariadb
Enable auto start at system boot time.
systemctl enable mariadb
Check status:
systemctl status mariadb
Now we need to run the security script.
mysql_secure_installation
When it asks you to enter MariaDB root password, press Enter key as the root password isn’t set yet. Then enter y to set the root password for MariaDB server.
How to Install LAMP Stack on CentOS 8/RHEL 8 – LinuxBabe
Next, you can press Enter to answer all remaining questions, which will remove anonymous user, disable remote root login and remove test database. This step is a basic requirement for MariaDB database security. (Note that the letter Y is capitalized, which means it’s the default answer.)
How to Install LAMP Stack on CentOS 8/RHEL 8 – LinuxBabe
Now you can run the following command and enter MariaDB root password to log into MariaDB shell.
mysql -u root -p **************************************************************
Install PHP and some common modules using the following command.
yum install php php-fpm php-mysqlnd php-opcache php-gd php-xml php-mbstring -y
Apache web server on CentOS 7 by default uses PHP-FPM instead of mod_php to run PHP code, so in the above command we also installed php-fpm. After it’s installed, we need to start it.
systemctl start php-fpm
Enable auto start at system boot time.
systemctl enable php-fpm
Check status:
systemctl status php-fpm
“Enabled” indicates that auto start at boot time is enabled and we can see that PHP-FPM is running. The php-fpm package installs a php.conf file in /etc/httpd/conf.d/ directory, so we need to restart Apache web server, in order to run PHP code.
systemctl restart httpd
We also need to run the following command to tell SELinux to allow Apache to execute PHP code via PHP-FPM.
setsebool -P httpd_execmem 1 Now upgrade to PHP 7 PHP 7.3 is available for CentOS 7 and Fedora distributions from the Remi repository. Add it to your system by running
sudo yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm sudo yum -y install epel-release yum-utils
By default, the enabled repository is for PHP 5.4. Disable this repo and enable on for PHP 7.3
sudo yum-config-manager --disable remi-php54 sudo yum-config-manager --enable remi-php73
Once the repo has been enabled, install php 7.3 on CentOS 7 or Fedora using the command
sudo yum -y install php php-cli php-fpm php-mysqlnd php-zip php-devel php-gd php-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json
Check version installed
$ php -v
************************************************************** Install and setup VSFTP Install vsftpd Then install vsftpd and any required packages: yum -y install vsftpd Configure vsftpd Now let’s edit the configuration file for vsftpd. Open the file with the following command: vim /etc/vsftpd/vsftpd.conf Disallow anonymous logins; this allows unidentified users to access files via FTP. Ensure that the anonymous_enable setting to NO: anonymous_enable=NO Enable local users to login, this will allow your regular user accounts to function as FTP accounts. Change the local_enable setting to YES: local_enable=YES write_enable=YES chroot_local_user=YES Exit and save the file with the command `:wq`, or with `:x`. Restart and Enable the vsftpd service: systemctl restart vsftpd Then set the vsftpd service to start at boot: systemctl enable vsftpd Allow vsftpd Through the Firewall firewall-cmd --permanent --add-port=21/tcp And reload the firewall: firewall-cmd --reload Change permissions on the users home folder: chmod a-w /home/.sites/

How to find Active Directory Search Base
To find out your user and group base DN, you can run a query from any member server on your Windows domain.
To find the User Base DN:
– Open a Windows command prompt.
– Type the command: dsquery user -name <known username>
(Example: If I were searching for all users named John, I could enter the username as John* to get a list of all users who’s name is John)
– The result will look like: “CN=John.Smith,CN=Users,DC=MyDomain,DC=com”
– In Blue Coat Reporter’s LDAP/Directory settings, when asked for a User Base DN, you would enter: CN=Users,DC=MyDomain,DC=com
To find the Group Base DN:
– Open a Windows command prompt
– Type the command: dsquery group -name <known group name>.
(Example: If I were searching for a group called Users, I could enter the group name as Users* to get a list of all groups who’s name contains “Users”)
– The result will look like: “CN=Users,CN=Builtin,DC=MyDomain,DC=com”
– In Blue Coat Reporter’s LDAP/Directory settings, when asked for a User Base DN, you would enter: CN=Users,CN=Builtin,DC=MyDomain,DC=com.
Syncback on Server 2012 as scheduled task doesn’t run
User Rights
You should also make sure the user account has the necessary Windows user rights. To do this, run the Local Security Policy control panel applet (in the Administrative Tools section of the control panel). If you are using the home version of Windows then you may not have access to the Local Security Policy control panel applet (Microsoft have removed the feature from home versions of Windows).
Make sure that the user account has the following user rights:
- Act as part of the operating system
- Log on as a batch job
- Log on as a service
Make sure the user account is not listed in the following user rights:
- Deny logon as a batch job
- Deny logon as a service
Setup network on Hyper-V virtual CentOS 6
Use system-config-network-tui and set up the card. If you perform a failover, you must connect the card in Hyper-V and then configure the card again.
If it does not come up, look in /etc/udev/rules.d/70-persistant-net.rules and see which “ethX” interface has the correct mac address. Either rename your ifcfg-ethx file in /etc/sysconfig/network-scripts or use system-config-network-tui to setup the correct “ethX” interface and restart the network.

Exchange 2013 mailbox move stuck at StatusDetail FailedOther
You have to remove the current move request and resubmit:
Remove-MoveRequest -Identity userID
New-MoveRequest -Identity “userID” -TargetDatabase “Mailbox Database 0422167200” -BatchName “userID” -BadItemLimit “200”
Cisco ASA Port Forwarding
Create and add your ports:
object-group service TEST tcp
port-object eq 443
Now create an access-list:
access-list outside_access_in extended permit tcp any interface outside object-group TEST
Create a static PAT mapping:
static (inside,outside) tcp interface 443 192.168.4.200 443 netmask 255.255.255.255
Create the access-group:
access-group outside_access_in in interface outside
ERROR: unable to reserve port 443 for static PAT
The issue here is that the http service on the ASA is runnnig off of the standard port 80. Login to the firewall and run the following.
no http server enable
http server enable 8080
Now you should be able to add a NAT/PAT on port 443 to another server of your liking. Just remember when you attempt to use ASDM to manage the ASA in the future to specify the new port 8080.
How to find and remove a Service on Server 2008, 2012 and 2016
Run command prompt as Administrator
Find the keyname with “sc getkeyname”:
C:\Users\administrator.LOCAL>sc getkeyname “Atlassian JIRA”
[SC] GetServiceKeyName SUCCESS
Name = JIRASoftware151216105308
Now delete the key using:
C:\Users\administrator.LOCAL>sc delete “JIRASoftware151216105308”
How to add a route to IPCop
You can add the route command at the end of the /etc/rc.d/rc.local file. The route will be added every time IPCop is rebooted but not everytime the interface is restarted. Good for a box with minimal changes.
root@ipcop: # echo “route add -net 10.10.0.0 gw 10.1.0.1 netmask 255.255.0.0” >> /etc/rc.d/rc.local
SCP files from one linux host to another

How to enable Zero-Handoff on Unifi
– For Zero Handoff Roaming, you’ll need to install the UniFi controller version after v3.1.x
– Next setup a new WLAN Group by navigating Settings > Wireless Networks
– Next add a new WLAN Group by click the ì+î. Now give a name and Enabled Zero-handoff to make your roaming WLAN Group.
– Finally just add the access points you want to participate in this roaming group to this WLAN Group and it should then work fine.
– After initial setup, the UAPs handles Zero Handoff Roaming, so it works independently of the UniFi Controller software.
UniFi – Run the controller as a Windows service
Readers will learn how to run the Ubiquiti UniFi controller software as a Windows service.
Windows services are often useful since they are “background” applications which don’t require any attention on the part of the end-user. In this way, the service will launch upon startup, without any intervention on the part of the user.
https://help.ubnt.com/hc/en-us/articles/205144550-UniFi-Run-the-controller-as-a-Windows-service
Or
1. Close any instances of the UniFi software on the computer. If the UniFi Network Controller was just installed, make sure to open the controller software manually at least once, or let it run at the end of the wizard. Once you see the message UniFi Controller (a.b.c) started, the controller may be closed.
2. Launch the Command Prompt as an Administrator. On Windows 10 this would entail right-clicking and selecting “Run as administrator”. Please see Windows documentation to identify the appropriate method for your specific Windows version.
3. Change directory to the location of UniFi in the computer using the following command (exactly as it is here, no need to substitute anything):
cd "%UserProfile%\Ubiquiti UniFi\"
4. Once in the root of the UniFi folder, issue the following command to install the UniFi Network Controller service:
java -jar lib\ace.jar installsvc
5. Once you’re at a new command prompt line, after it says “Complete Installation…”, issue the following:
java -jar lib\ace.jar startsvc
6. Close the command prompt window either by entering the exit command, or clicking the X.
7. To access the UniFi Network Controller now open a browser and go to https://localhost:8443. Alternatively, the desired interface IP, or FQDN that is mapped to that host (in place of “localhost”) may be used.
How to completely reset a Ubiquiti AP-LR.
To reset the UniFi APs, power them on, and allow them to fully boot. (In case powered by the POE adapter, make sure the cable on the LAN port of the adaptor is unplugged.)
After they’ve booted, press and hold the small reset button (located on the back of the device) for 25+ seconds.
Wait for stable Amber/White LED.(Now replug the cable into the LAN port of the adaptor)
This should reset the UniFi APs and put them back into a discoverable state again.
How to setup Zero Handoff on Ubiquiti Unifi.
UniFi has always supported roaming according to base 802.11 standards. However with Zero-Handoff Roaming enabled, clients can freely roam between UAPs without incurring any latency penalty as a result of the roam. The basic premise is Zero-Handoff enabled UAPs appear as a single AP from the perspective of the client, thus eliminating disconnection.
Zero-Handoff Roaming is available starting with v3.x.

How to setup static PAT (port forwarding) on a Cisco ASA 5505 8.2
If you are going to forward multiple ports, setup an object-group similar to the following:
object-group service DVR tcp
port-object eq 10554
port-object eq 8000
port-object eq 81
Then add your access-list:
access-list outside_access_in extended permit tcp any interface outside object-group DVR
Then add your static PAT statements for the services in your object-group:
static (inside,outside) tcp interface 8000 192.168.5.202 8000 netmask 255.255.255.255
static (inside,outside) tcp interface 10554 192.168.5.202 10554 netmask 255.255.255.255
static (inside,outside) tcp interface 81 192.168.5.202 81 netmask 255.255.255.255
Then add your access-group statement:
access-group outside_access_in in interface outside
I want to make a backup or copy of my VMware virtual machine. What is the best way to do so?
Answer
To make a backup copy of a virtual machine created with VMware, just copy the folder to another location. When you power on the copy (open the VM), you will be asked if you have moved the virtual machine or copied it. Select that you “Moved It”. This will keep all of the settings the same. If you select the “Copied It” option, a new UUID and MAC address will be generated, which could cause Windows Activation to come up and can also cause Linux machines to have problems with the Ethernet devices.
You will not be able to use a backed-up virtual machine at the same time as the original because you will have a MAC Address conflict on your network. If you need to be able to run the backed-up virtual machine at the same time as the original, you should make a copy using the “Copied It” option.
Perform a full backup on Exchange to purge logs
1. Open Command prompt as Administrator
2. Launch Diskshadow
A.Add volume d:

Backup all SQL Databases at once
Problem
Sometimes things that seem complicated are much easier then you think and this is the power of using T-SQL to take care of repetitive tasks. One of these tasks may be the need to backup all databases on your server. This is not a big deal if you have a handful of databases, but I have seen several servers where there are 100+ databases on the same instance of SQL Server. You could use SQL Server Management Studio to backup the databases or even use Maintenance Plans, but using T-SQL is a much simpler and faster approach.
Solution
With the use of T-SQL you can generate your backup commands and with the use of cursors you can cursor through all of your databases to back them up one by one. This is a very straight forward process and you only need a handful of commands to do this.
Here is the script that will allow you to backup each database within your instance of SQL Server. You will need to change the @path to the appropriate backup directory.
File Naming Format DBname_YYYYDDMM.BAK
DECLARE @name VARCHAR(50) — database name
DECLARE @path VARCHAR(256) — path for backup files
DECLARE @fileName VARCHAR(256) — filename for backup
DECLARE @fileDate VARCHAR(20) — used for file name
— specify database backup directory
SET @path = ‘C:\Backup\’
— specify filename format
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name NOT IN (‘master’,’model’,’msdb’,’tempdb’) — exclude these databases
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @name
WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @path + @name + ‘_’ + @fileDate + ‘.BAK’
BACKUP DATABASE @name TO DISK = @fileName
FETCH NEXT FROM db_cursor INTO @name
END
CLOSE db_cursor
DEALLOCATE db_cursor
File Naming Format DBname_YYYYDDMM_HHMMSS.BAK
If you want to also include the time in the filename you can replace this line in the above script:
— specify filename format
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
with this line:
— specify filename format
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112) + REPLACE(CONVERT(VARCHAR(20),GETDATE(),108),’:’,”)
Notes
In this script we are bypassing the system databases, but these could easily be included as well. You could also change this into a stored procedure and pass in a database name or if left NULL it backups all databases. Any way you choose to use it, this script gives you the starting point to simply backup all of your databases.
