MS Exchange 2003/Server 2003 -   Pulling large amounts of data from Internet

PNRT asked
Last Modified: 2013-01-03
Hi Experts.  I have a MS Exchange Server 2003 on Server 2003nthat is pulling about 500MB an hour from the internet even when there is no mail coming in.   If I reboot the server the problem goes away for about 3 to 4 hours then starts again.   I have virus scanned (Symantec and Eset)  and scanned with malwarebytes but nothing shows up.   I've used Wireshark to try and see packet details but theres nothing unusual.   Anyone got any ideas?
Watch Question

Check to see if any servers or Pc's are downloading updates like Adobe, Microsoft, RealPlayer, Apple.. There must be someting causing that traffic.

Check to see what ports are getting the most hits.


I've narrowed it down to this one server and have moved everything else on to other lines.  This is the only thing that now goes out through that line.  I've also disabled updates.

No, I was running it on the network.   I'll try it on the server

Yes that would be better

Alternatively, depending on your switches, you can set up a monitoring port and run the wires hark from your laptop

If you want more details on that setup then let me know


That would be apprecaited, thanks.  In the meantime I'll start with wireshark on the server
Is that server a DC?

Is it just replicating?

What apps are loaded that may pull down periodic updates?

Do any users have access to it that may be downloading or uploading files to their user share?


Yes it is a DC
There should be no other connectivity other than the local network (except for mail of course)
No other apps other than AV and Exchange
No users have access to this server
Thanks for the reply
