Hi Dave, After a big search I finally found a little note with the key :) I did a search in the microsoft support site and found the article which Microsoft released after I had contact with them. There are 2: http://support.microsoft.com/kb/842801/en-us http://support.microsoft.com/kb/843545/ I also spoke some other System administrators and it seems that the newest patch released by McAfee (patch 13, it is out for 2 weeks now) also solves a lot off known issues. Hope it helps you out. Greetz, Mark Meelhuysen ________________________________ Van: Dave stevens Verzonden: wo 7/19/2006 16:48 Aan: exchangelist@xxxxxxxxxxxxx Onderwerp: [ExchangeList] Re: Mails queuing, not been delivered Thanks Mark, It is in combination with McAfee enterprise, just not sure what version.

After repeated contact with microsoft it turned out to be the AntiVirus anyway, though i had stopped the services. I read below that you are using groupshield. is this in combination with McAfee 8.0i enterprise? Microsoft pointed me out to an entry in thje registry which we needed to disable.. and from the moment I changed the entrie the pending submission queue was processed again. I only regret that I dont know anymore which entry it was. Stupid.. Hope this helps you out a bit.. With kind regards, Mark Meelhuysen ________________________________ Van: Hans Maris Verzonden: wo 7/19/2006 10:38 Aan: exchangelist@xxxxxxxxxxxxx Onderwerp: [ExchangeList] Re: Mails queuing, not been delivered We have a similiar problem. Mails get stuck in the following queues: - Messages awaiting directory lookup - Messages pending submission I can't find a system in the crashes/hangs...( they are not on regular basis) In out case it is the inetinfo (IIS) process that hangs, and crashes when trying to stop the services. We opened a case and are working with Microsoft to find a solution. I already installed a lot of debugging tools that collected a lot of logs, but it seems to be not easy to point to the problem... It seems to me that SMTP becomes irresponsive in 'a certain condition', some kind of mail that messes up SMTP ??? What I do to come quick online without robooting: - Kill inetinfo.exe - Resart services If we find some solution I'll let you know...

Do you recall anything being updated installed or changed? ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Dave stevens Sent: Tuesday, July 18, 2006 3:56 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Mails queuing, not been delivered All services are running, and we have tried disabling Mc Afee, but no joy. Mails just seem to get stuck in the queue. The only way to get some of them moving is to reboot the server. Even trying to restart the sntp service would throw the server into an unresponsive state. This is getting pretty dire, and I am not quite sure what the problem is. I have instructed a reinstallation of Exch 2003 sp2. From what I can see the smtp service is not working as smoothly as I would want. Just wondering if it corrupt? I just dont know.
