Ok, I have more information now, here's the exact error message. After the message appears, it is noticed that the database has changed to single-user mode.
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC SQL Server Driver]Timeout expired
/include/myasp.asp, line 137
The lines in the asp look like this...
134 set conn = server.CreateObject("adodb.connection"

135 ' conn.connectionTimeout = 60
136
137 conn.open "DSN=XYZ;uid=sa;pwd=mypassword;"
138 SQL = "SELECT shopper_id from dcshopperinfo WHERE shopper_id = '"&clientShopperID&"'"
139 set rsShopper = conn.execute(SQL)
140 if rsShopper.eof or rsShopper.bof then IsInvalidShopper = true
141 conn.close
142 set conn = nothing
