Unable to write to the log file ex111021.log for site W3SVC1. Disk may be full. If this is a network path, make sure that network connectivity is not broken.
Although I have 22 GB of space free on the server's c drive, I still get this error, not sure why? IIS log file location is C:\Windows\System32\Logfiles
I sync Iphone with Exchange server and the log EX111021.log is I think logging details of sync.
But now sure why I get this error message?
