Group policy settings were overwritten by a higher authority (Domain Controller) to: Server and Policy NOT CONFIGURED

Hi,
I am having SCCM 2007 R2 environment. Network access is given on port basis like on 80,443,445,8530,8531, & netbios ports. I deployed patches on all the machines, whci ha re in 4 different OU's in AD. Some of the machines from one OU are getting following error in WUAHandler.log. While patches got deployed on another machines from the same OU successfully.


Its a WSUS Update Source type ({A54EBE4C-8BDD-423C-B703-FF6FF97EA862}), adding it.
Unable to read existing resultant WUA policy. Error = 0x80070002.
