Heres a hard one...
Posted on 2004-04-29
I have a small networking environment. The architecture goes as follows: I have a SBS 2000 along with other shared computers behind NAT, have a PIX firewall and an ADSL modem connecting to the Internet.
Heres the problem... From time to time the SBS Server is getting disconnected from the MODEM (i.e. Ping from the Server to the modem will not give me any replies, while from any other workstation to the modem and to the server and vice versa will reply very well). As well, any incomming mail will not arrive to the final destination which is - the server.
In a normal situation, I have good communications between all the devices in the network (i.e. server, workstations and the modem) and emails are getting to destined users.
I'll appreciate any help...
