I am posting here in the belief that changing DNS settings implies that the ISP involved (Orcon in this case) has deficient default DNSs.

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 4.2.2.1 (Preferred) and 4.2.2.2 (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-)

It means that the addresses we are returning to you for microsoft updates may be causing issues.
Changing DNS servers will mean you are served from a different CDN for that content.

Microsoft uses Akamai, which will change what nodes you are served from depending on DNS server addresses.

I dont use windows, but i will ask one of the team in the morning to do some tests around this.

This is happening (1, 2) with other ISPs and around the world.

It is not specific to a single ISP. It's a Microsoft problem.

Just confirming that Windows Update continues to work even though I have reverted to the 'obtain DNS automatically' setting.  I have also reinstalled  .Net Client 4 Framework.

So the problem was fixed simply by changing the DNS settings.

While it fixed one issue it also creates a lot of potential performance issues. With the world moving to CDN's for content delivery using your ISP's DNS servers is always the best option. Why? Because then CDN's know exactly where you're located and will serve you content from the best location.

If your ISP has a Google cache for example using DNS servers from another ISP mean your YouTube traffic will be fetched internalionally from the USA or Sydney when it should infact be local traffic which would be delivered far faster.

The fix only needs the DNS change once, then it can be reverted back to the original one provided by the ISP.
