Windows cannot load extensible counter DLL BlackBerry Router, Perflib cannot be found

After scheduled reboot on our BES servers, we start seeing below errors. After doing quick resource we were able to stop the errors as follows below.

Problem: BES server even log is logging 1023, BES seems to be working

Solution: we have done two things to fix the issue

  1. Make sure the register key is in place Open Register on the BES server and drill down to following key
  • HKEY_LOCAL_MACHINE\SYSTEM\Current Control Set\Services\BlackBerry Router\Performance
  • C:\Program Files\Research In Motion\BlackBerry Enterprise Server\BypassRouter\BlackberryRouterPerf.dll
  1. " if the DDL file is missing go ahead and add it at the end of the line "BlackberryRouterPerf.dll"
