Hello All;
We are running Microsoft Server 2003 R2, and using it as our DNS and DHCP (using AD). We had help setting up our domain, as my boss and I are no experts in Server Administration. Anyway, our Network was working perfectly, all computers on the domain could be seen by all other computers, shares could be set up, sharing printers was a simple task, etc. - until my boss took down the network over the weekend. I am not sure what he did, but we got the network back up and running, but you can no longer see any other computers on the domain, nor can you share printers attached to domain computers. What do I have to do to get this back, or what should I be looking at?
All I know of what he did was to install Peachtree on the server for a reason that I dont understand, and it blocked ports in the Firewall that took down the network. To get the network back, he disabled the firewall, but now we can no longer see any of the other computers on the domain, and all of our shares are gone, and people who print to other printers on the domain cannot do so. He may have made other changes in Windows Server, or the DNS, when attempting to get the network back before he figured out it was the firewall.
Please help.
Thanks
Todd Lerew
