connect to MSSQL2005 via ODBC

Installed SQL2005, connect via (the new) SQL Nativ Client ODBC Vers. 2005.90.1399.00 works, just as (the old) SQL Server ODBC-Driver 2000.85.1117.00. Works fine.
But from an other machine -there is no client installed - using driver 2000.85.1117.00 I get the message "Server dosn't exist or access denied"
How I can connect ? It is due to the fact of .NET FRAMEWORK 2 ?
Thanks!Sounds like the 'other' machine is your first network client - check your enabled protocols with SQL Server Configuration Manager.

Also, check your connection details include the instance name if necessary.

Also, what are the OS levels and authentication method?|||Hi, Mulhall. Indeed, it's the first network client W2K, connections to other sql2000 servers are o.k., to SQL2005 tried using TCP/IP-Protocol, tried Named Pipes and all others. Using the standard instance, no named, using SQL-authentication such as win-authentication, tried connection by server-name and by IP-Adress. OS-Ping works normaly.|||Have you verified using the Surface Area Configuration tool that remote connections are enabled?

Thanks
