When using a file sensor (Last Modified) on Server 2008 it's not getting the true last modified timestamp. On Server 2003 the last modified file sensor works great. I believe server 2008 changed the NTFS behavior to reduce disk I/O.
Using SMB or even locally on the server, the file doesn't show it's been updated (time stamp) if you refresh (F5) using windows explorer then the timestamps are updated locally and through SMB.
So PRTG doesn't report the true timestamp unless someone is refreshing the directory.
Any ideas on howto correct this problem?
