Today I met a problem which took hours to solve me but at last it was solved Alhamdolillah. The scenario was to test my deployment on the machine where there is no MOSS installed but only WSS 3.0, so  What happened was that I uninstalled the MOSS 2007 installation from my Virtual Machine (win2003 server), it uninstalled successfully and then I ran the WSS3.0 setup and chose Advance Installation and install it as an stand alone server (Where it creates a windows internal database that is not accessible to users , except to a few windows services) and then when I tried to Run the “Sharepoint Products and technologies configuration wizard” it slapped me with the following error.

“Failed to start the database service MSSQL$Microsoft##SSEE. Repair this product by selecting it from the Add/Remove Programs menu.”

I had never seen such an exception ever before so i was stunned but soon my buddy google told me about the occurrence of this problem and the remedy of it. I just needed to follow the steps mentioned below to resolve the problem and use My SQL 2005 DB as configuration DB for WSS 3.0. Just go to the command prompt and change the directory to  “C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN\” and execute following commands.

1. PSCONFIG  -cmd configdb -create -server <my server address>
2. PSCONFIG  -cmd adminvs -provision -windowsauthprovider enablekerberos

Command 1 tells the configuration wizard to use my server as the Sql Server for WSS 3.0 and configures the configdb on this server and second command provisions the Central Administration site with windows authentication enabled.  and then you click the Central Administration Site icon and it is there.
