Random IRC From Exchange 2000 Server

[rjoles]

Since installing Websense, we have noticed that our Exchange2000 Server machine is sending out random IRC connection requests. We have blocked IRC through Websense, but the server continues to try - sometimes 5 or 6 times a day, sometimes 4 or 5 times that. We are running Windows Server 2000 SP4, Exchange Server 2000 SP3, Symantec Mail Security Server. There is nothing else running on this machine - no file serving, no application serving, users do not have access to any shares on this machine. Symantec does not find anything virus-wise, but it seems to me that there must be something there. I've checked all of the running processes and they all check out as valid processes against other servers we have running. There is nothing in the startup or in the 'Run'. Anyone have any idea how to track this down?

Thanks,
