Background: Home network consisting of 1 Domain controller, 2 XPpro clients and 2 98SE clients. The DC had been running NT4 server, with a 3rd-party NAT program, and all was hunky-dory. I decided to play around with a win2k Advanced Server box as my server, so I clear all the client shares and drop all the clients off the domain. Then I remove the box that was running NT4 and plug up my new box that will have 2kAS on it. I install 2k Advanced Server, configure all the hardware, activate the build-in NAT, and create a user account. I then add this user account to the Domain Admins group. After doing this, I go to one of the XP boxes, and join it to the new Domain (different domain name, fyi) without any problems. Reboot for good measure, log in as Admin, add the domain acct to the local admin group, and then log back in with the Domain account. Everything looks great til I try to share a folder. I right-click, click Sharing, share the folder, click permissions, click Add to select names/groups. Lo and behold, the only "Location" available in the list is the local machine. For some reason, I cannot see the user list from the Domain Controller. I can't even type in the names, 'cause it gives me a "This location is not in the location list" error. Any insights on what I might be missing would be appreciated. Thanks.
