I'm using the following ADO lines to open a connection with some ODBC
'datasource'

Set conn = Server.CreateObject("ADODB.Connection")
conn.open datasource, "", ""
....
sql = "SELECT ..."
...
Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open sql, conn, 3, 3

When the 'datasource' is invalid, my NT 4.0 server easily gets into
infinite loop (inetinfo.exe)...

Is there any easy way for me to check whether the 'datasource' is
valid?  Or does 'conn.open/rs.open' ever returns any error message?

Thanks a lot!

Normally it will halt with an error if the DSN is not valid -- you must have
"On Error Resume Next" set.

If so, just check for Err=0 after the conn.open statement.

If not, something very strange is happening and we'd need to see more code.
