I have, over the last few weeks, being experiencing continual failures with Windows (7 Home Premium 64 bit) Update returning an unknown error code 8024402F. A search on Google gives a huge number of hits. Even a search on the MS support website gives many hits.
The short story is that the solution for me is to change the DNS settings (Network Connection Properties, IP version 4 properties, change 'Obtain DNS Server automatically' to 'Use the following DNS Server addresses' and enter 126.96.36.199 (Preferred) and 188.8.131.52 (alternate).
The long story is that I have spent the best part of 3 weeks trying to solve this problem - including stopping BITS and Windows Update services and renaming the softwaredistribution directory, and uninstalling .NET Framework 4 Client Profile. I have run countless MS fix programs from various associated KB articles and none worked. Its very frustrating that in Win 7 you cant use IE as an alternative access to Windows Update.
If 'Obtain DNS Server automatically' causes the use of DNS servers nominated by the iSP then I am sure that this indicates that Orcon has a DNS server issue that needs fixing - and that there may be other Orcon users similarly affected.
Disclaimer: My knolwedge of Domain Name Servers is as follows: they translate domain names to ip addresses. I know no more 8-)
