All Messages being rejected Exchange 2007

Hi

We suddenly have a problem with our exchange 2007 where all external to intenal messages are being rejected without reason, all was ok last night then suddenly nothing being received at all...

We do not have any Anti Spam filters turned on (never have)...

Sending internal to internal works ok, sending from internal to external addresses works ok, it's just receiving does not..?? No changes in firewall, nor updates to server has taken place.

Any ideas..??

Please have a read of my article - you sound like you are suffering from Backpressure!

Basically - you have probably got low on disk space on one of your volumes and Exchange has shut down inbound mail!

yes, alanhardisty, thats it.! Why didn't I see that.! AH.!

Whats the quickest way to find the largest files on the C drive (the full drive) so that I can delete what ever has filled it up..? Would that be exchange logs that has filled it up..??

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

My article has a way to turn off Backpressure - turn it off - get your mail flowing and then clear up.

Are you running an Exchange Aware Backup?  If not - the Exchange logs won't be clearing and then they will consume the disk space.

ServTechAuthor Commented:
Yes we run Exchange Aware Backup, plus the exchnage databases and log files are on a sperate disc (not the full c drive), there is loads of space on that drive.

Something has filled up the C drive, hence my question about large files size..?

Alan HardistyCommented:
Well - there is the usual Windows Search - but check out the logs on the c: drive or move WSUS if you have it installed.  That'll chew up about 30Gb if installed.

thanks alan, back pressure sorted, email on again. We don't use WSUS so its not that...

Just wondered if there is a better way of monitoring what is filling up a drive from day to day..??

Alan HardistyCommented:
Day to day - we use GFI Max to monitor volumes and report centrally.  You can look at the top level of c: and leave your cursor over the folder and it will tell you how full the folder is - then drill down the big ones.

Some graphical tools are available but I haven't any preferences.

You are welcome - glad you are up and running again quickly.

Keep an eye on those disks and next time you won't get bitten by the (ahem) 'feature'

Thanks for the points.
