On a multihomed computer that is running SQL Server 2000 Desktop Engine (MSDE), clients may be unable to connect to the server. If you attempt to make an ODBC connection to the server by specifying the server's IP address, the following error message occurs:
[DBNETLIB]SQL Server does not exist or access denied. [DBNETLIB]ConnectionOpen (Connect()).
This error may occur when an ODBC connection is attempted to a computer that has multiple network cards where MSDE is listening on one IP, but the Netbios name resolves to the IP address of the other network card on the same computer.
