Win2k3 Port check

Hi,

I have Win2k3 server, where ICS enabled. I have couple of third party applications installed in it. One of those very important is an email application. Which sync mails between the user and server. Our mail hosted by third party ISP. So for people who dont have internet access inside organization will configure them in this email application.

Very recently I started facing... all the ports getting closed after some time.

If reboot the server everything works fine.

After some time if telnet port no 110, i dont get welcome banner.

samething happens to RDP also.

Any idea to check how the ports getting closed. During this time I can ping the server.

If cmd > netstat -a

I am seeing pop, smtp and rdp listining!!!!!!!

The ports are accessible for some time and for some time not.

Once It go down, i cannot use those untill I restart the server.
