SharePoint Error Event ID: 104 – Failed to Connect to the Configuration Database

Error: When you attempt to join a member server to a Web Farm you receive the error below




Resolution:  More than likely you have either WSS installed on the server trying to connect or a previous installation of WSS/MOSS with Databases still mounted


  • Verify under “Add Remove Program” for WSS is not installed, In my experience there was WSS installed which was plugged into MSDE thus the Management Studio did not attach to.  Go ahead and uninstall WSS and run the Products and Technology Wizard again.
