Windows Update Error 80070643 & 80071A91 on all updates - Win7 64 SP1
Hi,
I've got a Win 7 pro 64 bit SP1 machine on a domain, pointing to a local WSUS server which has stopped installing updates. The update gets to the point in the progress bar where it should be installed but then returns failed with 80070643 & 80071A91 error codes. Currently there are 45 updates outstanding. All other machines on the domain receive and apply updates successfully.
If I try to apply updates 1 by 1, I get a mixture of the errors already stated depending on the update i'm applying.
I've run chkdsk & sfc /scannow.
SURT has been run.
Updates still coming back with the same error.
CBS log is 185Mb, so even zipped to large to attach, CheckSUR is reporting no errors detected.
Anti-Virus is: Sophos Endpoint 10.3
If anyone can help it would be massively appreciated!
Thanks,
Jack
