Recently was tasked with updating passwords on an older SharePoint 2007 farm. The fun part, Windows Server 2003 was the host OS. I hit a wall right out of the gate when I tried to run my STSADM command.
STSADM.EXE -o updatefarmcredentials -identitytype configurableid -userlogin “domain\SP_Admin” -password Cool@Password
Error: Access Denied
What the $#%##, I know I have full access to the farm and databases.
In Windows Server 2003, to launch the command prompt, right-click and select Run As. THEN, un-check Run this program with restricted access. Now run the STSADM command again.
