When attempting to start monitoring on a server you might receive the below error message:


Error: Input string was not in a correct format



The above error occurs since the counters are corrupt and not displaying their correct names instead just displays random numbers. A sample screen shot is attached below.

To overcome this issue you will need to run below command on the server that displays invalid information for counter names:

lodctr.exe /r %windir%\system32\PerfStringBackup.ini
