Error 1720 installing EMC Powerpath and PPME.

I was trying to upgrade EMC powerpath from Powerpath v5.3 to v5.5 SP1. I uninstalled 5.3 using the windows utility and was then unable to re-install the latest version. Found that the previous uninstall was not successful. When tried to install Powerpath and PPME got the below error:

Error 1721. There is a problem with this windows installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: PP_Writ_To-XML-UninstMode, location:.. \Powerpath””MAINTENANCE_MODE””MODE””0″”CUR_STATE””D..”

Hence, in order to fix the issue copied same installation folder from another working server and executed the file named “PPREMOVEALL.exe”

This removed all dependent files and folders with registry values. After a reboot, I was then able to install Powerpath 5.3 SP1 successfully.


VMware P2V or V2V gives error Unable to contact the specified host.

When you do a P2V or V2V of Windows 2008 server using VMware Converter you might get the below error:

Unable to contact the specified host. The host is not available, there is a network configuration problem, or the management services on the host are not responding.

In order to execute the conversion process, it is necessary to open the required ports on the source. This error would be displayed when the required TCP and UDP ports are not open.

Hence, the best solution is to disable the firewall to fix the issue.

In my case the issue was fixed using the below command.

NetSh Advfirewall set allprofiles state off


Upgrading Windows 2008 R2 editions from the command line without media.

Tested something new with Windows 2008 today. Windows 2008 has an inbuilt utility called the Deployment Image Servicing and Management (DISM) tool which does not require any media to upgrade the edition and just needs a reboot.

this is not possible on a domain controllers and only do upgrades, not downgrades.
Supported Windows 2008 R2 upgrade paths are:

Windows Server 2008 R2 STD -> Windows Server 2008 R2 ENT -> Windows Server 2008 R2 DC
Windows Server 2008 R2 STD Core -> Windows Server 2008 R2 ENT Core -> Windows Server 2008 R2 DC Core
Windows Server 2008 R2 Foundation -> Windows Server 2008 R2 STD

To upgrade, you need to provide a valid 25-character product key for the edition to which you’re upgrading.

To determine the installed edition, run:

DISM /online /Get-CurrentEdition

To check the possible target editions, run:

DISM /online /Get-TargetEditions

Finally, to initiate an upgrade, run:

DISM /online /Set-Edition: /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

So, for example, to upgrade to Windows Server 2008 R2 Datacenter from a downlevel edition, you would run:

DISM /online /Set-Edition:ServerDatacenter /productkey:ABCDE-ABCDE-ABCDE-ABCDE-ABCDE

After running the /Set-Edition command, DISM will prepare the operating system for the edition servicing operation, then reboot twice while it applies the changes to the operating system. After the final reboot, you’ll be running the new edition!

Fix RDP on Windows 2003 without reboot.

A very common issue on a daily life of a Windows server administrator is that the users complaining about RDP issue. If the issue is with Windows 2008, that’s fine as we can restart the remote desktop services to fix the issue. But the same issue on Windows 2003 is bit annoying.

However, I have found a solution which works perfect.

The fix: (remotely using command prompt)

tasklist /s \\servername /svc /fi “imagename eq svchost.exe” (locate PID for TermService)
taskkill /s \\servername /pid xxxx (may need /f to force, UAC might give problems as well)
sc \\servername start TermService

The Fix: (local, using command prompt)

tasklist /svc /fi “imagename eq svchost.exe” (locate PID for TermService)
taskkill /pid xxxx (may need /f to force, UAC might give problems as well)
sc \\servername start TermService

Detailed Information:

Open a command prompt
Type in: tasklist /svc /fi “imagename eq svchost.exe”
This will list the different instances of svchost.exe and the associated service and PID
Locate TermService and note the PID for it
Open Task Manager and go to the Processes tab. Then click View > Select Columns and check PID, then click OK
Locate the svchost.exe process with the PID noted in step 4, right click it, select End Process
Open services.msc

“Remote” tab missing from My Computer properties.

Recently, one of our server was completed with inplace upgrade from Windows 2000 to 2003. After the upgrade, when you right-click My Computer icon in the Desktop and choose Properties, the Remote tab was missing. Because of this I was unable to configure remote desktop settings and this was fixed by registering the DLL file using the below command.

regsvr32 %systemroot%\system32\remotepg.dll

If you receive an error stating that the module could not be found, or stating no registration helper is registered for this file type (which indicates a corrupt DLL), extracting a new copy from the installation CD should help.

To extract the DLL from Windows the installation CD, type this in Command Prompt


Note: considering X is you CD ROM and C as your Windows drive.
