Weird TCP/IP Problem

[edubiel]

I'm having a weird problem with a Milennium Workstation.

I can ping all the machines in the office except for the one that's running Winproxy 3. I get a timeout every single time. I thought maybe I had a bad connection at the winproxy machine.

However, I am also able to ping all machines in the office from the winproxy machine.

Removed the NIC Driver, All protocols, all DNS Info, then reinstalled-- Still no luck. Any Ideas?

Thanks

edubiel, would you let me add some theorical questions to yours :

1) is ping an service like others, I mean does it use a particular port ?
2) I know there are particular restrictions on ping with firewalls, is it the case with winproxy 3?

to you edubiel : is your Me workstation a winproxy 3 client ? are'nt all the services redirected to a single proxy service port ?

Actually, I'm only trying to ping the internal NIC on the winproxy machine. If I can't establish a TCP/IP connection to this NIC, I can't connect to the machine.

what zephan is saying , is probably:

if it is a proxy, it will let traffic through ,and not to,(depends what kind of proxy)

if it is there for security reasons, it could be blocking ping
