It appears I have a lot to learn.
Here are the basics: Windows 2003 R2 Standard, acting as a domain controller and file server. 9 users. Five static IP addresses.
I've never set up a VPN on 2003 server, and was using http://searchexchange.techtarget.com/news/...1069414,00.html as a guide. Right around step 6, all users lost communication with the server. At this point I had set up a group in AD to manage policies for VPN users.
What I'm stuck with now is two-fold, but one issue is critical: computers that were already members of the domain had no connectivity issues. All other workstations lost their name resolution - the server is still on the network and visible, but cannot be reached using its name; IP only. To get around this I added the IP address of the server to everyone's HOSTS file, but there has to be a reason name resolution went off the deep and no longer works.
Secondly, given that I still have no working VPN server, can anyone recommend a reference or learning materials on how to do this properly? I'd much prefer not to have the domain controller take on an additional role given that it already handles file serving as well as authentication, but to be frank I don't think the load would amount to much anyway.
Thanks in advance for helping a fledgling server admin!
