Need Help!

I have a setup of 4 servers. One being and email server and the other the
SPAM gateway. Everything was working well until a couple weeks ago. when
suddely no emails were getting through. troubleshot and realized that the
gateway was not processing any emails. check DNS Server and DHCP and all
looked good. did "nslookup" and that came back with the correct IP address.
Tried to ping the IP address and it times out. Reserved the IP Address via
DHCP and rebooted the server and all was well for about a day and then the
same thing. evenrtually added a seperate NIC and everything was well for a
few days, then the server rebooted for soem Windows updates last Friday and
we are back to square one.

The SPAM gateway can get out on the internet fine and ping other
workstatiosn and servers on the LAN just fine.

Stumpted!!

Checked even logs and they compalined once of the EVENT ID 1058 and
1030...but figured that was due to the faulty NIC... but cannot be. All other
servers were rebooted and still not luck!

need assistance!

Hello ss1001,

How is DNS setup on your servers? Did you run netdiag and dcdiag to see that
theire are no errors?
