I get the same basic issue on a regular basis with Exchange 2003/Windows 2000/GFI Mail Security 8. It happens absolutely every time the anti-virus (standard BitDefender and Norman) is updated. However, my slowdown rarely lasts more than about 30 seconds. I have similar hardware (dual xeon/2GB RAM) with about 1000 mail users - but I have never had the slowdowns last more than a minute.
I am quite certain that the problem rests squarely in GFI MailSecurity but it is not a big enough issue for me to consider changing to a different AV vendor. I've just assumed that the update had to stop/start STORE or some other critical service for the AV engines to update. In over three years of using GFI, I haven't had a single viri/worm/exploit make it past the virus scanner. With that kind of record, I will tolerate a few seconds of delay when the virus definitions are updated.

If you right click and choose cancel server request, it looks like all is connected for a minute or so, then it happens again no updates take place. If I right click on the outlook icon in the client system tray, it shows three connections to exchange server mail at least one of which will show multiple errors and an extended response time. Synchronization error log just shows "Network problems are preventing connection to the microsoft exchange server." I have windows 2000 sp4, and Windows xp SP1(fully updated) clients mosly running Outlook 2003 some in exchange cached mode and some not cached, as well as a couple Outlook xp clients. All have same issue. The server is available (shared folders, remote desktop). The Event log does not show any unusual errors - nothing that marks the start of this issue. The Outlook 2003 client shows connected but with a red exclamation on the system tray icon. - does not shift to disconnected. The Exchange server is a dual xeon 2.4 ghz, 2 gig ram. Processor usage does not go above 20%, memory usage is normal, and the server has only one nic (gigabit) on a managed gigabit switch. The whole network is only about 35 computers and three servers. The whole thing sits behind a checkpoint firewall, so the lan users are not going through a router or firewall to reach the server. All users are experiencing the same thing at the same time. After I reboot, all is well until the next morning sometime. I have Virus protection on the server but it is set to exclude the exchsrvr directories and subdirectories. I have GFI Mail Essentials and GFI Mail Security running I have tried disabling GFI Mail Essentials (stopped Services), but the problem still came back. Automated Backup has been suspended until I resolve the issue (arcserve brightstor). I upgraded office xp to 2003 in about three sets over the course of 5 days. It was only after the last set that I started seeing this issue, but all are installed off the same shared folder using the same Group Policy. I had two computers on the Beta 2 of Office 2003 for months did not see this issue. Exchange Server has been 2003 since the RTM release. I don't know what else to look at - anybody have any advice? _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&; lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
