I have 2 Macs running OSX on a W2K domain. I am using DNS. The problem that I'm having is that sometimes the Mac's can ping by name and sometimes they can't. It seems that they lose their ability to resolve names. I tried to modify the Hosts file, but it wouldn't let me even after changing the permissions. Also, in Outlook 2001 I tried to add the IP address of the Exchange Server instead of the name, but ti keeps reverting back.

Under OS X modifying the hosts file isnt as simple as just editing the file. Try using Hostal http://www.versiontracker.com/dyn/moreinfo/macosx/9732 or by looking at the macosxhints.com page for additional info on changing the hosts file.

It was a good answer, and it worked for most of the problem, but it doesn't take care of my problem with Outlook Express changing it's settings or the fact that they only intermittently resolve names.

That should have been Outlook 2001, not express.

Then you shouldn't have accepted the answer and and should have posted a followup question.

If the hosts file is set up properly it shouldn't be intermittently resolving domains, even if the machine isnt hooked up to a network. Have you tried deleting your Outlook preferences and re-configuring it?

Yes. I even removed Outlook completely and reinstalled it.

Removing Outlook, and reinstalling, doesn't delete the preferences file. Remove that manually.

Here's what worked: Added the Hosts file from Hostal, deleted all of my preferences in Outlook and set it up again, added my DNS servers in the TCP/IP settings in the Classic Environment (not just in OSX). It looks like that took care of all of the problems.
