I am unable to ping the server from several computers on my network.  How ever from the server I am able to ping the machine that couldnt ping the server.  I have two differnet subnets connected via T1 over the net.  The network layout is listed below.

Home:

10.151.1.1 - 255
Running DNS
Wins Server
AD


Remote location
10.151.4.1 - 255
Running DNS
Wins Server
AD
Used DNS server from Home location


I cant ping server names from the remote location to home but i can ping there IP address..  Any Ideas?

Hi ,

In order to ping by name, you need DNS to be able to resolve the name to an IP.  The dirty fix would be to add an entry to your lmhosts file that points the ip to the right name.  

Otherwise, how are you tunneling through from one to the other?  Are you using a VPN or another method? Or is the T1 a direct connection dedicated between the two networks?

ALright here is one that has me stumped.

I have a client that is running a simple network. One location, 192.168.1.x, 255.255.255.0 network. There are three file servers. One at 192.168.1.1, the next at 192.168.1.4, and the next last at 192.168.1.5. From a workstation with a static address 192.168.1.49 I can ping all three servers no problem, and then something happens, the .4 server will not respond to my pings, but is working fine from another workstation and then a minute or so later voila it begins to work again. I have sentup many ping -t's around the office to see if there is a pattern or something but nope. It just stops talking to one or more workstation out of the blue. This server is running exchnage 2000 and you can imagine the frustration as the clients get disconnected from thier email and can't get in for a minute or so.

The .4 server is running one NIC, has 3 but two are disabled, no IPsec, no TCPIP filtering, DNS works fine. No event log errors. The server was connected to a 3com 4900 switch at 1000mbs so I connected it to one of the 10/100 ports on the 3Com 3300 stack. I disabled autonedgotiation one both ends of the connection. I set the connection to 100Mbs/half duplex. but still acting wierd. I have tried changing one of the other nic's in the server and the problem is the same. I disable the nic, enable the other nic and setup the IP settings the same as the first NIC. I though maybe it was an exchange issue but with all of the exchange services disabled the problem is still there.

Please help.
