Exchange 2003 server running on Windows Server 2003.
While I was away from the office, there was a problem with disc space on the server and some of the log files from:
C:\WINDOWS\system32\LogFiles\W3SVC1 and C:\WINDOWS\system32\LogFiles\SMTPSVC1
have been deleted (Anything older that September is gone) and I don't really have a backup of the C:\ drive on that box, only the Exchange data.
Since the log files were deleted about once a day the server needs a restart otherwise we can't send/receive mail. When i go into System Manager and look in the Queues, there are just loads of messages stuck in there and the state is 'retry' but the queues never go down until the server is restarted, then it seems to work fine again for a few hours to a day until it happens again.
I'm assuming the 2 things have to be related and reading up on those log files they obviously shouldn't have been deleted. Is there anything I can do to get the server running properly again without the old log files?
EDIT: Couple of things from the event log:
