Problem: Clients not reporting to WSUS / wrong client version

sz-a

Hi,

Actually I have some single systems which are downloading no updates from wsus.

Things I have already tried:

- Reset Authorization with detectnow

- Reset SoftwareDistribution-Folder

- Reset WMI-Repository

- Reinstalled Standalone Version of WSUS client component (no error message on install, but timestamps of the components wuauclt.exe and wuaueng.dll are from 2015 (changed 20.10.2015, create/last access 11.11.2015)

I can see the following behavior:

- Systems connecting to WSUS ("Last Contact" on every reboot of the client) but "last reported" empty

- actually the Windows Update Client versions are:

     - on functional clients: 7.6.7601.23453 ( --> I don't know which KB provides this version for installing manually)

     - on Client with Error lower version: example: 7.6.7601.19161

- wuaueng.dll causes svchost to eat up around 50% cpu usage

How can I solve this? How can I reset Windows Updat eComponents to a version after fresh install?

A new installed Win7 SP1 updates correctly.

Thanks

The solution seemed to be:

1. Use the Windows Update Diagnostic: http://go.microsoft.com/?linkid=9830262 

2. Stop wauserv (Windows Update Service)

3. Download and Install KB3172605 manually and reboot. After that the version of wuaueng.dll is the correct one (7.6.7601.23453) and Update runs.
