I can ping from a workstation with NT4 to a Citrix-Winframe-server in the same local network. But I can't ping the other way around. The subnet is equal. The only difference I can see is that the Citrix has a default gateway (the router). Citrix canping to this router (the ws can do this too) and it can ping another NT-server that is in this local network (as can the ws as well).
Anybody any suggestions.
Thanx
George

Does the workstation run any protection like zone-alarm. I have had this problem with zone alarm.

Try doing a "traceroute" ("tracert

" in windoze) from wkstn to Citrix, and from Citrix to wkstn and compare the results. I think what you will find is that somewhere between these 2 systems, packets are being redirected. Perhaps the Citrix,for some odd reason, which you should be to figure out when you see it in action, thinks it ought to send the PING packets to its default gateway. My guess, however, is that the wkstn, when it sends the ICMP reply to the PING back to Citrix, is shipping those off in the wrong direction. Perhaps it is getting bad information about the Citrix's source address (if the Citrix has a 2nd IP address???).

Hope that helps...

Sorry for the misunderstanding, but it's the citrix that can't see the ws. The other way around there is no problem. The ws can see others in the same subnet. Citrix can only see an NT-server and a router, not the workstations. Please try again.
Thanx

Check the routeing table on the Citrix machine (from a cmd.exe prompt type "route print")Check that the route for the local subnet is going through the Citrix's network card IP address (the Gateway and Interface entries). Also check that the metric for this route is 1.

Tried that, no problem. Works fine.
Still not pinging the other machines.
Thanx anyway

Try and ping the workstation from another machine on the Citrix lan. If you can check the default gateway on the citrix machine.
Also be sure that the router hasn't got a access list configured or that there is a firewall somewhere in place.

good luck

That's it: the norton firewall prohibited to ping. Disabled it and no problem anymore.
Thanx

Sorry Martin, I rated your answer to soon as not exeptable. It was after all.
