Replicate Hyper-V between Workgroup servers

Enabling Hyper-V between two workgroup servers requires issuing self-signed certificates with makecert.exe and a registry key to bypass the revocation check.

The reason why makecert is required is because the certificate Enhanced Key Usage must support both Client and Server authentication, and the default IIS certificate CSR wizard does not include the client EKU.

First download makecert.exe from here: https://www.navuser.com/Data/makecert.exe

Machine #1
1. Generate a root cert:
makecert -pe -n CN=PrimaryTestRootCA -ss root -sr LocalMachine -sky signature -r PrimaryTestRootCA.cer

2. Generate a self-signed cert from the root cert:
makecert.exe -pe -n CN=HV2 -ss my -sr LocalMachine -sky exchange -eku 1.3.6.1.5.5.7.3.1,1.3.6.1.5.5.7.3.2 -in PrimaryTestRootCa -is root -ir LocalMachine -sp “Microsoft RSA SChannel Cryptographic Provider” -sy 12 HV2.cer

3. Disable the revocation checking since that won’t work on self-signed certs:
reg add “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\Replication” /v DisableCertRevocationCheck /d 1 /t REG_DWORD /f

Machine #2
1. Generate a root cert:
makecert -pe -n CN=RecoveryTestRootCA -ss root -sr LocalMachine -sky signature -r RecoveryTestRootCA.cer

2. Generate a self-signed cert from the root cert:
makecert.exe -pe -n CN=HV1 -ss my -sr LocalMachine -sky exchange -eku 1.3.6.1.5.5.7.3.1,1.3.6.1.5.5.7.3.2 -in RecoveryTestRootCa -is root -ir LocalMachine -sp “Microsoft RSA SChannel Cryptographic Provider” -sy 12 HV1.cer
(Note: even though it outputs a .cer file, it automatically inserts into the LocalMachine certificate store, so there is no additional import step)

3. Copy the PrimaryTestRootCA.cer from Machine #1 and then run this command: certutil -addstore -f Root “PrimaryTestRootCA.cer”

4. Copy the RecoveryTestRootCA.cer from Machine 2 and then run certutil -addstore -f Root RecoveryTestRootCA.cer

5. Disable the revocation checking since that won’t work on self-signed certs:
reg add “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\Replication” /v DisableCertRevocationCheck /d 1 /t REG_DWORD /f

6. Now you can select the self-signed certificate in replication on both servers.

How To Know Which Process is Using a File or Folder in Windows

Resource Monitor

For Windows 7 and above, you can use the built-in Resource Monitor.

Open Resource Monitor, which can be found

By searching for resmon.exe in the start menu, or
As a button on the Performance tab in your Task Manager

From CPU tab, use the search field in the Associated Handles section

When you’ve found the handle, you can identify the process by looking at the Image and/or PID column. You can then close the application if you are able to do that, or just right-click the row and you’ll get the option of killing the process (End Process) right there.

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.

Permissions that need to be set to allow automate users home directory creations

share1 When you configure home directory for user (from “Active directory users and computers” – in Windows 2000/2003/2008/2012 domain or “User manager for domains” – in NT4 domain), you should add root share that will contain the user home directory – \\servername\users$\%username%. To allow automatic creation of this home folder, there need to configure correct NTFS and Share permissions on home folder root share.

Right click the folder > Properties > Sharing > Advanced Sharing. Name the share and add a “$” to the end to make it a hidden share.

Click Permissions on the share.

To allow automate home directory creations, please make sure to apply this security settings on the root folder that should contain the user home directory.

Administrators: Full Control
System: Full Control
Authenticated Users: Full Control

Now click OK > OK to get back to the Folder Properties.

Now we need to configure the NTFS permissions, so we need to be on the “Security” tab of the folder we created earlier.

1. Turn off inheritance on the folder and copy the permissions. You do this by:

a. Click the Advanced button found on the Security tab.
b. Clear Allow inheritable permissions to propagate to this object check box in the Advanced Security Settings dialog box.
c. Click Copy when prompted by the Security dialog box.

2. Click OK to return to the Security tab. Ensure we have the following permissions set:

Administrators: Full Control

How to set Internet time on Windows Server 2008 R2

To configure an internal time server to synchronize with an external time source, follow these steps:

Change the server type to NTP. To do this, follow these steps:
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\Parameters\Type
3. In the pane on the right, right-click Type, and then click Modify.
4. In Edit Value, type NTP in the Value data box, and then click OK.
Set
AnnounceFlags

to 5. To do this, follow these steps:
1. Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\Config\AnnounceFlags
2. In the pane on the right, right-click AnnounceFlags, and then click Modify.
3. In Edit DWORD Value, type 5 in the Value data box, and then click OK.
  
  Notes
  - If an authoritative time server that is configured to use an AnnounceFlag value of 0x5 does not synchronize with an upstream time server, a client server may not correctly synchronize with the authoritative time server when the time synchronization between the authoritative time server and the upstream time server resumes. Therefore, if you have a poor network connection or other concerns that may cause time synchronization failure of the authoritative server to an upstream server, set the AnnounceFlag value to 0xA instead of to 0x5.
  - If an authoritative time server that is configured to use an AnnounceFlag value of 0x5 and to synchronize with an upstream time server at a fixed interval that is specified in SpecialPollInterval, a client server may not correctly synchronize with the authoritative time server after the authoritative time server restarts. Therefore, if you configure your authoritative time server to synchronize with an upstream NTP server at a fixed interval that is specified in SpecialPollInterval, set the AnnounceFlag value to 0xA instead of 0x5.
Enable NTPServer. To do this, follow these steps:
1. Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\TimeProviders\NtpServer
2. In the pane on the right, right-click Enabled, and then click Modify.
3. In Edit DWORD Value, type 1 in the Value data box, and then click OK.
Specify the time sources. To do this, follow these steps:
1. Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\Parameters
2. In the pane on the right, right-click NtpServer, and then click Modify.
3. In Edit Value, type Peers in the Value data box, and then click OK.
  
  Note Peers is a placeholder for a space-delimited list of peers from which your computer obtains time stamps. Each DNS name that is listed must be unique. You must append ,0x1 to the end of each DNS name. If you do not append ,0x1 to the end of each DNS name, the changes that you make in step 5 will not take effect.
Select the poll interval. To do this, follow these steps:
1. Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\TimeProviders\NtpClient\SpecialPollInterval
2. In the pane on the right, right-click SpecialPollInterval, and then click Modify.
3. In Edit DWORD Value, type TimeInSeconds in the Value data box, and then click OK.
  
  Note TimeInSeconds is a placeholder for the number of seconds that you want between each poll. A recommended value is 900 Decimal. This value configures the Time Server to poll every 15 minutes.
Configure the time correction settings. To do this, follow these steps:
1. Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\Config\MaxPosPhaseCorrection
2. In the pane on the right, right-click MaxPosPhaseCorrection, and then click Modify.
3. In Edit DWORD Value, click to select Decimal in the Base box.
4. In Edit DWORD Value, type TimeInSeconds in the Value data box, and then click OK.
  
  Note TimeInSeconds is a placeholder for a reasonable value, such as 1 hour (3600) or 30 minutes (1800). The value that you select will depend on the poll interval, network condition, and external time source.
5. Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\Config\MaxNegPhaseCorrection
6. In the pane on the right, right-click MaxNegPhaseCorrection, and then click Modify.
7. In Edit DWORD Value, click to select Decimal in the Base box.
8. In Edit DWORD Value, type TimeInSeconds in the Value data box, and then click OK.
  
  Note TimeInSeconds is a placeholder for a reasonable value, such as 1 hour (3600) or 30 minutes (1800). The value that you select will depend on the poll interval, network condition, and external time source.
