One of our 16 sites cannot connect to the network. We even put in a new server 3 days ago. They can connect for 3 days, then the server goes down for them. This has been continuous. When you go to logoff, their name is there. They cannot access email or anything. What did we do wrong? We use a DNS for internet, WINS, Gateway. We use routers and those have been checked. This has been happening for 4 months. Before that, there were no problems

Hi,
Firts of all I suggest that ping from m/c which has problem to m/c which has no problem.Check that if there is any packetloss is happenning.If happening quiet possible that it is hardware problem.Check it with replacing nic and cable with good one bascially from m/c which has no problem.If u find that replacing nic and cable does not slove problem then check hub/switch ports.
Hopfully this will solve ur problem.

Could use a few more details here. You mention a new server. Was this installed at the problem site? What type of connection are you using (DSL, frame-relay, ISDN)? When you say the server goes down for them, do you mean the server at that site crashes, or that they lose connectivity to the PDC at a different site? If the server at that site crashes, what error messages is it showing in the Event Log?
On the basis of what you have provided, I would suspect an issue with your link. What do you do to get the users at the problem site reconnected?
Were there possily any configuration changes done at the problem site around the time the problems started?
Hopefully this will give you some directions to look in.

Thanks for the info. This helped us in that someone at that site did do config changes before and did not relay that to us that they changed the subnet address and they kept changing the domain names. We did not look for the obvious.
