“Configuration Manager Admin Console can’t connect to the Configuration Manager Site Server”

Sometimes, when we re-install or upgrade Configuration Manager Admin Console. It shows following error on console.

Go to following location and open SmsAdminUI.log
C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\AdminUILog\SmsAdminUI.log
[6, PID:5544][######] :The performance counter ‘# exceptions’ was not found
[6, PID:5544][ ######] :The performance counter ‘# exceptions’ was not found
[6, PID:5544][ ######] :The performance counter ‘# result objects in memory’ was not found
[6, PID:5544][ ######] :The performance counter ‘# exceptions’ was not found
[5, PID:5544][ ######] :The performance counter ‘# images’ was not found
[1, PID:5544][ ######] :The performance counter ‘# images’ was not found

How to Fix:
Above problem explains that performance counters store is corrupt. We need to rebuild performance counter.

1. Uninstall Configuration Manager Admin Console.
2. If possible delete registry key: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\ConfigMgr10
3. Run LODCTR /r on Command Prompt
4. Once command completes successfully, we can re-install Configuration Manager Admin Console
5. If LODCTR /r fails with error code 2, we can try following actions on command prompt.
    reg query “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\PERFLIB” /v “Last Counter”
    if %errorlevel% == 1 reg add “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\PERFLIB” /v “Last Counter” /t REG_DWORD /d 0x0 /f

 reg query “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\PERFLIB” /v “Last Help”
 if %errorlevel% == 1 reg add “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\PERFLIB” /v “Last Help” /t REG_DWORD /d 0x0 /f

5. Run LODCTR /r on Command Prompt again, this time, it should work.
   C:>LODCTR /r

I hope this will help.
