Error With IIS and Sql Server 7

Hi
I want to connect with IE5 to my SqlServer7 database through IIS.
When i tried to connect, the message
[ODBC drivers][names piped] No SQL Server found is displayed.
I don't why ?
All my services are running.
Can you help me please ?
Thanks

Are you running any server script which makes the data connection ADO or something thru ASP ?
