Customer reported that vRanger was not deleting the Exchange logs correctly and they were filling up the C: drive to the point where there were only a few megabytes left on the drive. The logs all started with EX********.log
vRanger was handling Exchange logs properly; the logs were in directories under C:\WIndows\System32\LogFiles and were the IIS logs from the HTTP server, which had a lot of traffic because of OWA.
Advised customer that these logs could safely be deleted and suggested installing a VBscript that would, on a daily basis, go through the log files and delete any files older than 1 week old.
