To synchronize the time between the servers:

1. Create the following .bat files :
2. • TakeTime.bat, consisting of the following script :
     
     nfcmd localhost getsingle Controller IsActiveServer | find "false
     
     if errorlevel 1 goto end
     
     net use \\<Remote_Server_Channel_IP_Address> /user:<Full_Domain_Name>\<Admin_Account> <password>
     
     net time \\<Remote_Server_Channel_IP_Address> /set /yes
     
     :end
     
     For example:
     
     nfcmd localhost getsingle Controller IsActiveServer | find "false
     
     if errorlevel 1 goto end
     
     net use \\10.0.0.1 /user:QA.lab\Administrator password
     
     net time \\10.0.0.1 /set /
     
     :end
      
   • SyncTime.bat, consisting of the following script :
     
     @echo off
     
     for /L %%j in (1,1,2) do (
     
     sleep 600)
     
     for /L %%i in (1,1,9999999) do (
     
     taketime
     
     sleep 86400)
     
3. On the Secondary server, copy the two .bat files (TakeTime.bat and SyncTime.bat) into the %Program Files%\VMware\VMware vCenter Server Heartbeat\R2\Bin folder.
4. If it is not installed already, download and install the Windows Resource Kit Tools found at http://www.microsoft.com/downloads/details.aspx?familyid=9d467a69-57ff-4ae7-96ee-b18c4790cffd&displaylang=en.
5. Copy the sleep.exe file from the Windows Resource Kit Tools installation folder (located in the %Program Files%\Windows Resource Kits\Tools, into the %Program Files%\VMware\VMware vCenter Server Heartbeat\R2\Bin folder).
6. In the Windows StartUp Menu, add a shortcut to the SyncTime.bat file. This can be added directly in the %Documents and Settings%\Administrator.Domain\Start Menu\Programs\Startup folder.
7. Repeat this procedure on the Primary server replacing the <Remote_Server_Channel_IP_Address> with the channel IP address of the Secondary server to provide for synchronization after a switchover.
