Thread:Project talk:Support desk/Asp Project ADODB.Connection is returning null after media-wiki installation

I am working on a asp site. It is working fine with windows 7 but after installation of media-wiki its ADODB.connection is returning null value. I have checked odbc settings for both 32 bit and 64 bit and its working fine. The error comes when ADODB try to open a connection with sql server. Can anyone help?
