Exchange 2007 outgoing mail crashes intermittently

About once or twice a week, my outgoing mail crashes on Exchange 2007 (on a SBS 2008 Server), and no mail can go out. I have 8 Exchange users on this network. I used to reboot the server to fix it. Now through trial and error (mostly error) I have found if I restart the DNS Server service, and then the Microsoft Exchange Information Store, this solves the problem. But I have no idea why. At first I thought it was my Avast SBS anti-virus program (because I had to restart that service too) and it was happening almost every day. So I switched to Trend Micro Worry Free and the problem only occurs once or twice a week now. But of course that is once or twice too much. Please help, people are getting really frustrated.

Thanks, I will try that. Given the nature of this issue, it might be a week before I get back to you.

So far it seems you are correct. This new version of SBS is a nightmare. I never had all these problems with 2003.

Sadly NIC offloading was added in 2003 as well and has just as many problems. I put equal blame on hardware manufacturers for claiming to support the offload features and allowing their drivers to attempt it and on Microsoft for not making their driver qualification tests include more rigorous testing for this feature before approving a driver. Alas, it is what it is, and this is the state we are in.
When it works, task offloading can provide better performance. But when it doesn't....sheesh. Ugly problems arise. Glad that helped resolve your issues.

You are so right about ugly problems. Installers and consultants beware with SBS 2008. It's the new Vista. I get new complaints almost everyday. That never happened with the 2003 version. With Exchange 2010 already out, an updated version of SBS will hopefully be forthcoming (and soon). Thanks again!
