Someone on EE asked me to install ComboFix (http://download.bleepingcomputer.com/sUBs/ComboFix.exe
) to check/remove infection in my computer. After installation and running it, my SQL server 2000 is not running anymore. I get the following error message on the start up of my computer:
"SQL server could not find the default instance(MSSQLSERVER) - please specify the name of an existing instance on the invocation of sqlservr.exe
If you believe that your installation is corrupt or has been tampered with, un install then re run set up to correct this problem..."
My .net applications are not working anymore as they can't connect to the database. Is there any fix for this?
