I have an Exchange 2010 server and it stopped receiving email. I've been told that I'm having a problem with resources. It looks like the database file is 39 GB and I have 22 GB available on my Exchange drive. The exact error that I'm getting is "4.3.1 Insufficient system resources". I have 60 GB available on my C drive. I have 32 GB RAM and I'm currently using only 25% of my physical memory. I'm not able to start the Exchange Transport service because it says starting. I cannot stop it either because it's not an option. Please help me out as I need to get this Exchange server working again. I did run through the best practices analyzer and it mentioned that the CPU is running at 1900 MHz and it's a 3000 MHz. It mentioned that if my CPU uses Intel Step technology, I should ignore this warning. I think that I have a newer CPU that uses this technology. Please let me know if there's any other info I can provide to help diagnose the problem. Thank you!
