If SBS 2003 has not been service packed up to Windows Server 2003 SP2 (How to obtain the SP) yet, there is a cautionary tale to be had about running chkdsk /f on that server:
- Microsoft KB: 913034: The Chkdsk.exe utility incorrectly identifies and resets security descriptors in Windows Server 2003
If the bug rears it’s head, then it is quite possible the server will not come back up if the system partition had chkdsk /f run on it. This goes for any other partition chkdsk was run on that may have critical data on it relevant to a proper OS boot too.
If the partition was client data oriented, there could be a need to either reset the permissions on the entire partition, or recover it from the most recent backup to save on all of the work resetting permissions.
This is another good reason to test those service packs and then deploy them on our client servers!
