These settings are from win98. Use this as a guide as to where to find your NIC settings. The MaxMTU setting below is not present in the registry out of the box, you have to add it by hand. (And people think windows is easier to use!) NT probably has different registry key names that handle NIC behavior. By the way, if you plan to use Samba to map windows network drives, again, you'll have trouble with the out of the box settings. NT with service pack 3 and greater and win98 encrypt the network logon passwords, and Samba gags on them. You have to enable "allowplaintextpasswords" (this is from memory) on the windows machines and Samba will allow access to the drives. Microsoft's knowledge base actually has a good article on the subject. Search there for samba and you should come up with the right article.
