What I would suggest is you get a Netmon capture of when SMTP is disabled and 
then another when SMTP is enabled and see what traffic could be causing the

HELP -- I'm beside myself and hope I'm overlooking something simple.

Have an Exchange 2003 with SP1 that worked well for a week and now when the 
virtual SMTP server is started, the Internet slows to a crawl.

Here's what I've done and noted:
-- No significant entries in the Event Log -- a couple entries for a blacklist, but am in process of cleaning that up -- no other dnsblacklists.
-- No large numbers of entries/messages in Queues of ESM
-- Have a Cisco PIX 501 on outside, and enabled logging... Not much there 
either in terms of activity
-- Have Symantec 10 and Mail Security on this which I believe are configured 
-- there is really just not a lot of traffic going on.

It appears that the main problem is when the smtp service and/or smtp virtual 
server is started. Any Internet access is very SLOW and they Terminal Service 
users (which is on another server) are complaining.

Any suggestions greatly appreciated!!
