MS Exchange 2007 seems to stop receiving mail after a number of hours

Dear Experts,

We have an Exchange 2007 server that works brilliantly for a few hours, but then after 4 or 5 hours seems to stop receiving mail from external sources. I've tried stoppping and starting all the exchange services to remedy this but it does not seem to work. Messages are still received internally. The only cure that I can find is to to a full re boot of the server. If it helps, when this error occurs, users at home can no longer access the OWA element (web outlook).

If anybody can provide any solutions/help/advice or could just point me in the right direction I would be very grateful.

Hi there,

The info contained in these kb pages don't really relate. To be honest there are no entries in any section of event viewer that suggest a possible cause.

Does anybody know of anyway I can debug this. A log file or event log I can look at?

Cheers

I have installed rollup 6 for Exchange 2007 but the error still exists.

Just to reiterate - my exchange 2007 server works perfectly for a number of hours before it seems to stop receiving any external originating email. It also does not allow any remote users to connect via OWA. I've tried reatrting every Exchange service but no joy. Is exchange stopping this traffic for a reason?

The only fix is to reboot.

Help!

I'm getting this error in my Application Event log.

Process MSEXCHANGEADTOPOLOGYSERVICE.EXE (PID=1936). Exchange Active Directory Provider failed to obtain DNS records for forest DC=counthill,DC=org,DC=uk. DNS Priority and Weight for the Global Catalog servers in this forest will be set to the default values 0 (priority) and 100 (weight).

Could this be the problem?
