We have a WSUS server 3.2.7600.226 and all client/workstation WUAgent version is - 7.4.7600.226. We have not updated our WSUS server according to http://support.microsoft.com/kb/2720211KB
Now problem we are facing here is , there are around 4 Client systems which are having WUAgent version - 7.6.7600.256. These system are not getting properly synced with our WSUS server. When I check the windowsupdate.log file I get below error message on all the 4 servers.
WARNING: WU client failed Searching for update with error 0x800b0001
MY question is ,
1. I belive WSUS server is the one which pushes WUAgent on all the client/workstation systems . Am I right?
2. WUAgent version - 7.6.7600.256 will not work with WSUS Version - 3.2.7600.226 ? Do we need to have WUAgent version - 7.4.7600.226? (I think so)
3. How these 4 servers got 7.6.7600.256 , As I belive WSUS server with version pushes WUAgent - 7.4.7600.226?
