Can't connect to one server

I have 3 Win 95 clients that cannot connect to just one of our servers (which happens to be the mail server). These clients can see every other server on the network however. When I ping the server, I get a "host not found" error. When I am at the server and try to ping the client, same problem.

I have tried all of the usual steps: reinstalled NIC driver, Networking protocols, replace NIC card and cables. I even tried to plug the machine into different port. I rebooted the server multiple times and rebuilt the WINS database.

Anyone have any suggestions or have similar problems?

Host not found is a naming problem. Have you tried pinging using the IP of the server instead of the name. Are each of the machines registering with the WINS database?

Are all the computers running the same protocols? TCP/IP, IPX/SPX ect and is the IP address dynamic, are you using DHCP, WINS or do you have static IPS IP address that do not change? Try buying one new nic card and try it in one of them, all three being bad is a long shot.

Scottdo10 is right. It is a naming problem. Go to the DNS settings under IP properties in network control panel and compare these settings to the other computers that work properly.

Simple troubleshooting will do....check & compare the settings on the working systems & rectify accordingly.

GoodLuck.

I've seen this before. In out building we had three separate groups of Class C IP addreses.

The issue is in routing. In my case we were using a Netware 3.20 server with Novell's IP services to act as a router between all three subnets.

I'm not certain what you might be using but were I you, I'd be checking routing first.

might want to check the subnetting. if the subnet is setup incorrectly one range of ip's would be okay but your mail serv might be out of that range. might want to (on a weekend) shut down a server these three can see and then change the ip on the post office and see if they can now see it.

good luck!
