Multiple NICs / local macine name bound to wrong adapter

I have a Windows 2000 server installed in a VM partiton and it has two virtual apapters.  The server name is "app01".

One adapter has a 10.0.0.x address and the other adapter has a Class A assigned IP address - we'll just say it's 17.x.x.x (not really the first octect).  The 10 dot address is used solely on a fiber backbone and is used to perform system backups.  It does not route to the 17 dot address range.

The problem is that the 17 dot address resolves fine from a remote workstation via DNS.  So, if I ping the machine name 'app01mybusiness' from anywhere in the network, the name resolves the 17 dot address.  However, if I go onto the local machine, and ping the same machine name "app01" it returns the 10 dot address.  

The application installed on the server is a 3-party application (which means we cant modify it that much), and it registers the machine name in a remote database.  Since it is entering the 10 dot address in the database, subsequent clients can't connect to the application server.

In the adapter, the 10 dot does not have a default gateway or DNS servers filled out.  The 17 dot does have a gateway and a DNS server listed.  

Bottom line:  I need to get the local machine to resolve itself to the 17 dot address.

Since I'm a newbie, I don't have a lot of points to give so I'm throwing in all I got.

Try making a DNS host entry and point it to the 17 address for that machine and see if the clients can ping it then.  

If they ping the 17 address do they get a response?

What is the order of the adapters you are using?  Ie, Adapter 1 is 10, adapter 2 is 17?

Is it VM Ware you are using and when you ping the machine from in VM Ware it responds with 17 but from the host machine that VM Ware is running it comes as a 10?

You might want to check the binding order to see if you can change the adapter bindings to see if that works.

Thanks for the help.  The last part about the binding order - I suspected that it was something like that but I didn't know where to find out how to change it.  I googled "change binding order" to find the kb article: http://support.microsoft.com/?kbid=266771.  As much as I've tooled around in Win2k, I never considered that there was another menu in the Networking window.
