Cannot start local probe



I try to run PRTG Network Monitor. Core server starts normally. After installation, I can't connect to local probe, because Local probe does not start automatically after installation.

The Event log contains the following entry: Timeout (30000 milliseconds) waiting for the prtg probe service to connect.

When run from the command line I get the message:

The application or DLL C:\Windows\system32\traffic.dll is not a valid Windows image [...]

dll installation local-probe not-started start-issues startup windows-service

Very likely, the traffic.dll is damaged. On the Windows command line, execute the following command to solve the issue:

sfc /scannow

Afterwards, the Windows service "Local probe" should start normally.

For details about the sfc command, see Description of Windows XP and Windows Server 2003 System File Checker (Sfc.exe)
