IP Networking

Hi

I know this problem is more likely some windows problem but it has also something to do with unix.

We have a windows nt environment wich uses AIX (unix) machines as file servers (samba). In our windows network environment we nicely see al the unix file servers via the 10 MB network. Last month we've put a 100 MB network card in al of our machines and the thing we wanna do is the following:

If there is a 100 MB connection (use it automatic)
If not use the 10 MB connection. But how can we tell windows or samba to use it this way??

Thanks for any help!!

Greetings

Mark

Couple of questions;

Which machines did you upgrade, the NT ones or the IBM ones?

What system handles the DNS (NT or AIX), or are they exclusive?

We have upgrade both systems. Our DNS runs on a AIX and our Domain controller runs on a Windows NT.
