Hi folks. Our Exchange is down. I've been troubleshooting since yesterday. Its SBS 2008 running Exchange 2007 on one server. All Exchange roles and DC/GC are on the same physical box. Currently, the Transport service starts and then stops. I am running a local nt backup to try and have a recovery point plus free or clear any transaction logs.
A little background: Users started complaining yesterday about email access - they could send out, and send/recv internally, but no incoming mail was getting through. I tried to use telnet from a remote computer to test smtp on the server. When I connected via telnet, and did the helo, mail from:drkuhl...@yahoo.com I was getting the "insufficient resources 4.3.2" message I did a shutdown and restart on the server No luck. So I started googling and found some blurbs about modifying the edgetransport.exe.config file and setting "EnableResourceMonitoring" value="false" to see if things got better while working to free up resources and stop what I think is a "back pressure" situation. Since that didn't help, I put the backup copy of the edgetransport.exe.config file back in place. Now getting "connection refused" with the transport service not being able to stay started. And we can't send/recv internally or externally now. I don't know if the service issues is currently because of the backup running but wanted to get some feelers out to try and work on later after it finishes if I still can't get the service to run. The event attached below seems to indicate that a file is locked or in use, maybe because of the backup running? Any help or pointers would be appreciated. Thanks Don K Here is a snip of one event relating to the transport service failure.
