SelfUpdate_Failure_Software Synchronization_Windows Update Client failed to detect with error 0x800b0001.

Dear community,

Im running WSUS 3.0 SP2

I have some windows 7 clients in the network that get this error. I am unable to reslve the issue.

I have this error in C:\Windows\SoftwareDistribution\ReportingEvents.txt

{2B7E33C5-F220-4AB9-8BB9-FE1BDE91F896}    2012-08-21 11:17:29:246+0200    1    148    101    {D67661EB-2423-451D-BF5D-13199E37DF28}    1    800b0001   SelfUpdate    Failure    Software Synchronization    Windows Update Client failed to detect with error 0x800b0001.

I tried the Fix it utility from microsoft. It detected an error and claimed to have fixed it but it is still not resolved.

When I do wsusutil checkhealth It say everything is fine.

If you have any sugestions to resolve my issue it would be very much appreciated.

Kind regards,
