>>We have narrowed this down to a connection protocol problem. The software is trying to connect using the Named Pipes Network Library but we require TCP/IP. I have not been able to locate where this setting can be made globally in NT. The only place we have seen it is when setting up a DSN.

Well, I would like a cleaner solution but for now, we will just create a DSN for the connection and specify TCP/IP which will toggle the switch for other similar connections. For us and setting up new machines, we can modify the "ghost" used to set up the machines to include this. However, I should think there is a way somewhere to specify the default other than Named Pipes, but I haven't found it yet. If I do, I'll let you know.
