Wan no Longer avaliable on 2003 server

Hi I installed the enterprise solution a couple of months ago at two different sites. both of which have the same versions and mirror server setup.

Since this installation nothing else has been done to the server whatsoever.

Routing and Remote Access is enabled on both machines for purpose of VPN only and remote deskop is enabled as well.

In the last few weeks one of the sites has started refusing any access to the outside world either in or out but local network is fine. my main concern is that the server is not able to update because of this and the client machines are not updating either as they access through the http port.

Has anyone experienced this, and is it likely to be nod causing it. no other firewall software is on the machine as the router acts as firewall and yes this is deffinately wrking as it should be.

 

Hello,
is the IMON icon actually grey and not red or green?

 

IMON is grey
DMON / EMON is red
AMON / NOD32 is blue

When i hit the update button is just runs through the list of servers, any pings i send come back as 'destination net unreachable' yet i can ping the router
