Windows Server 2012 Essentials : After Transmog SILSVC Error
May 2, 2013 3 Comments
The SILSVC should be started automatically but it is stopped.
I researched the issue at the time and also raised a bug, which was is still open. I was reminded about the issue again today so i decided to blog the solution as searching for the forum post took too long.
When booting up your computer after a Transmog you will see the following error in the System Log.
The service should be removed as part of the Transmog process, that is, the process that removes the 25 User limit inherent in Server 2012 Essentials. Unfortunately it only appears to remove the files associated with the service, and not clean up the registry.
If you take a look in the Services console, you will see the SILSVC and notice that there is a failure in the description.
The fix for this is made slightly more complex because when you try to access the registry section for this service, you are presented with an Access Denied message.
This leaves us with a couple of options, one being attempting to remove the registry key in safe mode, however this also does not allow access to the SILSVC registry key. So, really what i meant was one option.
The solution i used was to boot to the installation media, and use the repair option.
You need to chose the Troubleshoot option, then chose the CMD Prompt.
In the CMD, we can enter the Registry Editor by typing regedt32
Now we need to load the Registry Hive from the WSE Server.
Expand Computer, then select ‘HKEY_LOCAL_MACHINE’
Now click on File, and select ‘Load Hive’
We can now browse for the registry of our Essentials Server.
You can type in the path, or browse the directories, the path you want to go to is D:\Windows\System32\config
The file you want to load is called ‘SYSTEM’
You will then need to enter a name to identify this in the Registry Editor, i am just calling mine Essentials Server.
You can then browse through this exactly as you would for any other Registry edit but as this system is not booted into Windows we will want to look for CurrentControlSet1 (and you can also edit 2 if you want to)
Inside CCS1 look for Services, and inside Services, look for SILSVC. You can see now that we have full access to read this key, and work with it. Now we can delete it.
As i said you can also repeat this for CCS2 if you want to.
Now we can close down Registry Editor and type Exit to go back to Windows.
This time on boot up we should not see any errors relating to SILSVC. We can also confirm this service is now no longer present in the registry.
