Unable to Uninstall Project Server 2007

·         Click Start >> Run >> Type ‘RegEdit’

·         In Registry Editor browse to HKEY_LOCAL_MACHINE >> Software >> Microsoft >> Shared Tools >> Web Server Extensions >> 12 >> Secure >> ConfigDB

·         In ConfigDB folder locate three names Default , dsn & Id.

·         Rename dsn to something else. Let’s say dsna.

·         Then Uninstall Project Server and it works.

·         Run SharePoint Configuration Wizard.

·         In this scenario, while running SharePoint Configuration Wizard do not use psconfig command. Best option is to run using the UI.
