Enable Time Synchronization Between Windows (VM Guest) and ESX (Host).

This is in continuation to my previous post RDP Connection on a virtual server

As discussed earlier there was an issue with the AD authentication and connectivity. It was all because of the different time zone set on an ESX host and the guest operating system. Changing time on DC was not recommended by the AD Team as the impact was unknown and similarly we have no clue on the impact due to time change on ESX cluster. Hence, I decided to manually do the time sync between the ESX host and Guest machine.

Time sync status was validation using the command:
VMwareToolboxCmd.exe timesync status

Enter the command to enable or disable periodic time synchronization.
VMwareToolboxCmd.exe timesync Enable/Disable

We executed below command to fix the issue
VMwareToolboxCmd.exe timesync Enable

Note: VMTools installation directory on Windows is C:\Program Files\VMware\VMware Tools.

Thanks,

RDP Error – The connection cannot be completed because the remote computer that was reached is not the one you specified. This could be caused by an outdated entry in the DNS cache. Try using the IP address of the computer instead of the name.

Unable to connect to the Remote Desktop. Server operating system is Windows Server 2012 Standard R2. When we try to RDP, we get the below error message:

The connection cannot be completed because the remote computer that was reached is not the one you specified. This could be caused by an outdated entry in the DNS cache. Try using the IP address of the computer instead of the name.

There was two server with same configuration and setting but one of connecting to RDP with AD authentication whereas the other was not working. One was physical and the other was virtual hosted on an ESX host.
RDP on physical was good and the issue was with the virtual host. It was confirmed that the issue was due to time latency.
Therefore, this issue was due to the time difference between the virtual machine and the NTP server set on an ESX host.
This issue was later fixed by synchronizing the server time with the ESX host.

Note:
If you do not wish to have auto sync, disable the Windows Time service or block the outbound port 123 on your local firewall.

Windows could not finish configuring the system.

Recently, I was installing Windows 2008 R2 on a HP ProLiant DL380 Gen9 server. Found that the server was throwing an error message stating “Windows could not finish configuring the system.”. When you click on “OK”, servers gets automatic reboot and shows again the same error.

When searched on google, I found that this error message occurs with Windows Server 2008 R2 operating systems if the system contains a registry key that is larger than 8 kilobytes (KB). A Hotfix for this problem is available from Microsoft

KB981542

In my case it was during a clean install of Windows OS, hence it was fixed following the steps listed below:

When you find the error message stating that the “Windows could not finish configuring the system” appears on your screen:

1. Hold down the SHIFT key and press F10 (SHIFT + F10) to open command prompt.
2. At command prompt type: cd oobe (& press Enter).
3. Then type: msoobe (& press Enter).
4. Finally Restart your computer.

You will see your machine back with CTRL+ALT+DEL screen.

Windows 2012 Network Share: The specified network name is no longer available

Shares created on Windows Server 2012 R2 are are inaccessible from Windows XP, Windows Server 2003 or Windows Server 2008.

When you try to access the share you will get an error message stating “The specified network name is no longer available”. Windows 2012 will not accept traffic from an older operating systems.

In rorder to fix the issue, a registry setting on Windows Server 2012 R2 must be modified as listed below:

Back up the Registry Hive/Key and make the following change:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\DependOnService

Original Value: SamSS Srv2

Change to: SamSS Srv

Note: Just delete the 2

After making the change, reboot Windows Server 2012 R2

Note: You may also need to reboot the clients/servers involved
