PRTG Core Service does not start in timely fashion

The trial version of PRTG has been working but I am approaching the end of the trial and, since I am using this at home with fewer than 100 sensors, I would like to continue to use the freeware version. However, the PRTG Core Server Service will not start. When I try to start the Core Server in Windows Services, I get the error message "Windows could not start the PRTG Core Server Service on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion." I have tried rebooting, uninstalling/reinstalling, and several other suggestions from your Knowledge Base and Google searches. Please help.

Hi Datippin,

There is a known issue which effects the start of the core server. Please navigate to the directory "C:\Program Files (x86)\PRTG Network Monitor\64 bit" and check if there is a folder named ".\snmptemp\mib_indexes". If this is the case, rename the directory and try to start the service.

If such a directory does not exist, kindly check if there is a NET-SNMP installation located in the directory "C:\usr\".

We'd appreciate your feedback if the service starts correctly afterwards.

Best regards, Felix

Hi there,

Please open the Event Viewer of Windows and search for Errors under "Windows Logs > Applications". Is there any Error related to PRTG? If so, please post the upper details of the Error (which Applikation caused the issue, which DLL and so on).

Best regards.

Felix,

Renaming "mib_indexes" solved the problem. Thank you!

If you have an existing NET-SNMP installation on your system, the environment variable %SNMPCONFPATH% might have been set as well. You can check this in a cmd shell by typing:

    echo %SNMPCONFPATH%

If it returns a path i.e. D:\usr\etc\snmp, you're gonna have to have a look at the file snmp.conf found there, and see if "persistentDir" has been set in it.

On my system it has been set to "persistentDir D:/usr/snmp/persist"

This means PRTG will store its temporary MIB indexes in D:\usr\snmp\persist\mib_indexes and not in .\snmptemp\mib_indexes as suggested above.

I deleted the files found there (they were corrupt), and then I was able to start both the core server and probe services again.

The developers should take a look at this, as I think it's unwise that PRTG's NET-SNMP library uses the very same directory as a pre-existing NET-SNMP installation on the system for storing its temporary files.
