The Microsoft recommended solution for this is to insert disc 1, run setup, and remove the SBS 2003 component. This will leave a plain Win 2003 server without the shutdown issue. However, when I attempted to do this, setup errored out indicating that I was trying to upgrade to an older version which was not possible. Removing service packs may have worked, but here is a faster work around taken from a guy named Alan (http://social.microsoft.com/Forums/en-US/whssoftware/thread/af4fc3b4-bb50-4c5e-b09a-72ef2c3ac687)
I've found a slightly more elegant solution to this problem rather than just
aggressively killing the process until Windows gives up trying to start it
again, and I'd like to share it in the hope that Google will re-index and pick
it up for others to use. You may have noticed this service cannot be disabled
via the MMC snap-in.
My search term on google was: how to stop the SBCore
service. Anyway, down to business…
- Tools you'll need – Process Explorer from http://www.microsoft.com/technet/sysinternals/ProcessesAndThreads/ProcessExplorer.mspx
As you probably know, you have a service called SBCore or "SBS Core Services",
which executes the following process: C:\WINDOWS\system32\sbscrexe.exe. If you
kill it, it just restarts – and if you try and stop it you are told Access Denied.
If you fire up Process Explorer, you can select the process and Suspend it, now we can start to disable the thing. Run regedit and expand the nodes until you reach the following hive /key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SBCore Right click this, hit permissions and give the "Administrators" group on the local machine full access ( don't forget to replace permissions on child nodes ). F5 in regedit and you'll see all of the values and data under this key.
Select the "Start" DWORD and change it from 2 to 4 – this basically sets the service to the "Disabled" state as far as the MMC services snap-in (and windows for that matter) is concerned.
Next, adjust the permissions on the file C:\WINDOWS\system32\sbscrexe.exe so that EVERYONE account is denied any sort of access to this file. Then go back to process explorer, and kill the sbscrexe.exe process, if it doesn't restart – congratulations!
Load up the services MMC snap-in and you should find that "SBS Core Services" is stopped and marked as Disabled.
Note: When you run Process Explorer through Terminal Services, you are unable to suspend the process. I had to go on site to perform this process.
