With a few SBS 2003 to 2008 migrations going over the 21 day limit (unfortunately due to third party support on line-of-business applications) we found it necessary to use the below to stop the SBS 2003 server shutting down every hour. I do not recommend this or support this as it is in breach of Microsofts EULA – however in some scenario’s it may be critical to ensure a smooth decommissioning of the old SBS 2003 server.

The below is the error log you should see:

Event ID: 1001
Type: Error
Source: SBCore
The server was shut down because it did not comply with the EULA. For more information, contact Microsoft.

To disable we followed the below:

  1. Download the Process Explorer tool from SysInternals – Here
  2. Load Process Explorer and look for the SBS Licensing Service – C:\Windows\system32\sbscrexe.exe
  3. Select this service and Suspend it – you should find the service greys out
  4. Open Regedit and expand the following key – HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SBCore
  5. Right click this Key and add the Administrators group giving them Full Permission to the key (refresh this and you should see all the key entries now)
  6. Select the Start DWORD and change it from 2 to 4 (this sets the Disabled state)
  7. Open a File Explorer window and browse to the C:\Windows\system32\sbscrexe.exe file
  8. Right click this and load Properties / Security
  9. Add the Everyone group and set the Deny permission for Full Access (should then tick the sub permissions)
  10. Go back to Process Explorer and now kill the sbscrexe.exe service – this should now be disabled
  11. Check the SBCore service via services.msc – it should have a disabled state and now longer be running
  12. Job Done.

    Awesome! I got bit because user’s use UNC names for file access, and the new server was going to just have an alias for the old name. I initially tested successfully with Win7, but it turns out XP machines don’t do alias names by default without a regkey. This gave me some extra time to get that reghack deployed and retry the migration.
    And I swear the 21day reg change didn’t get picked up :/

    Best resolution. People who just want it to be server running a application in the existing domain environment.

    Perfect! Thanks a million. I removed active directory on a SBS 2003 server and couldn’t figure out why it kept shutting down. Hopefully new machine arrives soon.

    Thank you! It works for me!

    A vendor dragged their feet and wasn’t able to migrate a core application in time… so big kudos to this fix. thanks!

    Thanks for posting this. You’d expect this to be outdated by now… but there are still SBS 2003 servers out there!

    I’ll say this kindly….. I LOVE YOU!!!!!!

  16. 21/04/2015 at 11:11 AM Paul

    Nice one. Red face saved. Gives me a bit longer to migrate this old bucket!

  17. 22/05/2015 at 10:47 PM Scott

    Yep… This is still a thing that happens, happened today.. Thank you for this post x1000

    Thanks so much for detailing this. Thought the old girl was getting annoyed with the young kid on the block (Server 2012)!

    Thanks a million. Decommissioning several SBS 2003 with the July 14 thing, this has come in very handy!

    Great! This was very handy…….

    Same problem for me here – third party taking ages for their work and we have the succeeding server up and ready (and also in use – so no possibility to temporarily shut down again). Thanks a lot for saving me from a shutdowning server 😉
