I have a server running Windows 2003 R2 SP2. I can ping it from any computer on the network. My problem is that it acts as a file and print server, but none of the other computers on the network can access these files or printers. I've done some searching and these are the things that have been suggested and the results.

Make sure a firewall isn't blocking anything; There isn't one in place aside from Windows and it is turned off.

Check the DNS; I used nslookup with the IP Address and the server name and I got the same results, so that's not the problem. I also make sure to use the IP Address just to avoid DNS problems.

Telnet into the server from a client; I'm not sure if this worked or not. I used telnet servername 445, as the article suggested. The cmd screen cleared and left me with a flashing cursor. After about a minute I got the normal prompt on the next line. I've never used telnet before so I don't know if it worked or not, but I didn't get an explicit error message.

A general fix I've ran into before is to release the IP Address, flush the DNS, and renew the IP Address. Where I work, this seems to fix a lot of issues, but it didn't fix this one.

I've tried mapping the drives through Windows Explorer and the command prompt, but neither works. In command prompt, I get the error: Multiple connections to a server or shared resource are not allowed. In Windows Explorer, I get the error: The network path \\servername\share cannot be found. I've also tried to access the server through the run box. When I do I get the error: \\servername\share is not accessible. The network path was not found.

It is also worth mentioning, the server is experiencing a near identical problem. I can ping any computer on the network, but cannot access shares made on those computers from the server. I did this for testing purposes when the issue started, so fixing this direction of connection isn't a priority, but I feel this is relevant to the overall issue. When I try to use the run box to connect to the client's share from the server I get the error: \\clientname\share is not accessible. The network is not present or not started. The Windows Explorer and command prompt errors are the same as above.

Any and all help is greatly appreciated. Thanks in advance.

EDIT: Sorry for the single slash. I had typed two, but I guess HTML saw it as one. I had to put three for it to show two. It wouldn't let me add a comment so I just included this edit.

EDIT 2: Sorry, it still won't let me add a comment. It is part of a domain, and I'm sure that credentials aren't the issue. I've tried going in with the local and domain administrator accounts.

EDIT 3: Yes, Scott. I was at the aforementioned server when I made the question, but went back to my office afterwards. I'll see if I can find that registration email. Sorry for the trouble.
