Requesting Help with Network Connection Problems (W2k3 R2)

5 pts.
Microsoft Windows Server 2003
I have a 30-user average office network running on a Windows Server 2003 R2 server. The server is running AD, DNS, DHCP and WINS on a single box running as the domain controller. (In the future I plan to add a second domain controller to reduce the number of single points of failure.) This is a single-homed box behind a firewall device. While the box has two NICs I have disabled one of them. I am having major intermittent problems with several computers on the network unable to connect to the server. One third to one half of the users on the network are reporting intermittent problems connecting to the network. Here are some clues: 1) Sometimes users can connect, sometimes they can’t. Sometimes simply shutting down and restarting two or three times may resolve the problem, other times it won’t. At least half the users report no problems connecting to the server. 2) The server is no longer listed when browsing the network but the workstations are. However if I Start/Run \servername then all the server’s resources are listed and accessible. This is only so on the computers that have no problem accessing the drives. That is, the logon.bat file works fine for them but if I browse the network the server is not listed. 3) I have three switches on the network. The problematic workstations are spread across all three switches so it isn’t a faulty switch. 4) The only Vista user can connect to the server but the network access is extremely slow. I tried connecting her computer to another jack with a different cable in the event there was a cabling problem but that had no effect. She was able to connect fine until about a week ago. 5) DNS is handed out via DHCP. The only DNS server for the clients is the DC. The DC then forwards to the ISPs DNS servers for resolution of external addresses. 6) Two users have reported that all their printers are missing. I have the printers set to deploy with the domain controller group policy. Worked fine for them and all others but stopped working for these two. Thanks for any help. I’ve tried all I can think of to no avail. Bill

Thanks. We'll let you know when a new response is added.

I have one word for you DNS.

Ok so its an acronym for three but you are having DNS issues. I just saw this on a network that a friend configured. Your primary DNS for each client on your AD network needs to be your AD/DNS box. If it is not your querries for internal resources may go out to the internet and trust me they wont tell you where your printers or servers are!
