Maybe some one can help me here. I am having truoble reaching a server on a network. Basically I can ping it, but only intermitanly. Even if I hard code the route using "add route" it still doesnt work. I am pinging via IP address, just to be sure it wasn't DNS related. I talked to both our ISP's and they haven't added any Deny commands in the routers.

I don't think it's a patch cable -as I cannot get out to the whole network, But I can get to all other internet sites. Has any of you had this problem before? I am at witts end !!

Basically my client computers go out to the internet via a T-1, and I am trying to reach a network that is local to us physically, but is on the public internet. I think it may be a routing issue.

Thanks..

Questions:

1. What kind of server are you trying to reach.
a. Do you have access to the server?

2. When you ping the machine with intermittent results, are you trying to ping from 1 client machine to server or multiple client machines to server.

3. On what machine did you add the route?

If you added it on a client machine, don't forget that the server must be aware of the route.

In this scenario I would use tracert instead of ping.

Let's see where your packets are getting dropped. I usually use the -d switch.

Run tracert -d x.x.x.x from multiple clients to the server, then run it from the server to some clients or gateway of your network.

Other stuff... Is nat/proxy involved?, IPSec/Filters? Have you triedfrom local gateway to remote gateway then local gateway to remote server?

Try using a router. That should help you out. the router can be used to see other networks.
