What to do if PRTG's automatic cluster update fails due to removed files?



Your Vote:



In my log files, I find the following:

2010-08-24 12:33:27.600  Defaulting to Abort for suppressed message box (Abort/Retry/Ignore):
                          C:\Program Files\PRTG Network Monitor\PRTG Probe.exe
                          An error occurred while trying to rename a file in the destination directory:
                          MoveFile failed; code 2.
                          Das System kann die angegebene Datei nicht finden.
                          Click Retry to try again, Ignore to skip this file (not recommended), or Abort to cancel installation.
2010-08-24 12:33:27.600  User canceled the installation process.
2010-08-24 12:33:27.600  Rolling back changes.

In a cluster setup, PRTG automatically deploys a new program version of the PRTG Probe.exe or PRTG Server.exe files to all nodes.

Using a heuristic detection, some anti-virus software scanners judge this procedure as a potential risk and remove the files before they can be deployed. This results in a log entry as shown above.

Please configure your anti-virus software to allow execution of the PRTG files on all nodes.
