Exchange users not receiving email

My exchange 2007 users stopped receiving email today. I went through the troubleshooting assistant and it failed the exchange mail acceptance test with error 4.3.1 insufficient system resources. The drive where the mail store is located has plenty of space, so I poked around the web and found out I needed to edit the edgetransport.exe.config file to resolve this. Apparently changing enableresourcemonitoring from true to false will do the trick. Only problem is that when I make the change, I can't save the file. I get "cannot create the C:\Program Files\Microsoft\Exchange Server\Bin\EdgeTransport.exe.config file. Make sure the path and filename are correct"
Stuck here.

Maybe the file is in use. Try to stop the Exchange Transport Service.

It possibly a permission issue on the folder. Check if the account you are logued with has write/modify rights on this specific folder.

The two issues are very likely related. I wouldn't change the config file, but whatever is preventing you from saving the file (permissoins issue, corrupt/failing dirve, etc) is also preventing Exchnage from saving emails. Something significant has happend or changed on the partition that holds the exchange config and data.

Got it. Created a new file and replaces instead of just editing. Restarted services and I'm back up. Thx.
