Are your WSUS Update clients failing because BITS is stopped? Then, when you go to start it, it isn’t even there? Here’s the fix.Open the Windows Search tool, copy/paste the following and then click Search: qmgr.dll
Search should show that file in the following locations:
You may only see qmgr.dll in C:WINDOWSsystem32.
Go to Start, Run and copy/paste: regsvr32 qmgr.dll and click OK
Do the same with this file: regsvr32 qmgrprxy.dll
Reboot the system and then copy/paste this command into the Run field:
%windir%System32rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 %windir%infqmgr.inf
If you’re prompted to insert the Windows installation CD, ignore that and in the dialog box at the bottom, change the path to C:WINDOWSServicePackFilesi386
** Change the path to C:WINDOWSsystem32 if qmgr.dll was only present in that location.**
Restart the PC again and then go to Services and you should be able to see BITS in the list.
Double click it and then on the General tab, click the Start button to try and start the service manually. This is just a test to ensure that it’s working correctly.
If you get Error 2: cannot find the file specified, go to Start, then Run again and copy/paste the following command and then click OK:
Reg add HKLMSYSTEMCurrentControlSetServicesBITSParameters /v ServiceDll /t REG_EXPAND_SZ /d %windir%System32qmgr.dll
Reboot again and then try once more to start BITS. It should work properly now, but in the unlikely event that it fails again, run the following command and then hit Enter:
Reg add HKLMSYSTEMCurrentControlSetControlBackupRestoreFilesNotToBackup
Reboot once more.
