My local probe shows a "disconnected" status. It does not recover. What can I do?
This article applies to PRTG Network Monitor 9 or later
Change Mac Scan Setting
By default, on services startup, PRTG tries to detect all available network adapters on the system running a probe (this includes, for example, the PRTG core server).
On few systems, this might lead to an exception so that the probe cannot fully connect to the core server. In this case, please try to disable the initial detection of available network cards.
Caution: Please backup your system before manipulating the Windows registry!
- On the system running the PRTG core server, open the registry editor.
- For a 64-Bit Windows system, go to
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Paessler\PRTG Network Monitor\Probe\
- For a 32-Bit Windows system, go to
HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\Probe\
Note: For PRTG 8 you might see the values in the additional sub-key V7 or V8.
- Add a new DWORD value with the name NoMacScan.
- Set this to 1 to disable the initial search for network adapters.
- The new setting is active after a restart of the core server Windows service (see PRTG Administration Tool in the manual).
Hello, I have similar problem, with my local probe - it is disconnected for most of the time, and any of other sensors are not working at this time. The most strange thing is that whenever I login to the webpanel, everything starts to work, and after logging off it stops again. I have changed above settings (NoMacScan) in system registry but it did not help. I am using PRTG 188.8.131.525 on Windows 7 64bit.
Could you please forward us your system log files for analysis? You can find the same under
XP/2003: C:\Documents and Settings\All Users\Application Data\Paessler\PRTG Network Monitor\Logs (System)
Vista/2008: C:\ProgramData\Paessler\PRTG Network Monitor\Logs (System)
Please send the Logs(System) folder as a zip file if possible.
If you have changed the location of the data folder in the past or if you can not find current log files in the above location, please check your data path in the PRTG Server Administrator Tool on the PRTG server.
please send the logs to [email protected]

Hi, i have found a Solution for me.
I have just started "services.msc" and searched for the service: PRTG Probe Service. After i have restarted this service manually the Local Probe has reconnected after 1 min.
Maybe its worth a try.
Info: My LocalProbe was constantly disconnected after the Local-Probe-Computer has been shutted down and powered up again later.
I get this issue. I solve the issue by enabled prtg services (in services.msc) I don't know why the service won't start automatically as it's configured
Please check the Event Log, especially "Application" for any occurring errors during the start of the service. Are there any displayed?
