Problem running Windows Update

Hi

I have a Windows Server 2008R2 that I cannot update. When I try to update I get the following error message:

Code 80072F78 Windows Update Encountered an Unknown Error

I have not been able to update this server for a long time, but it is very out of date and really should be patched.

It is joined to a domain that used to have a WSUS server. This does not exist anymore. I have edited the registry keys telling it not to use WSUS and also removed the WSUS server entries.

Additionally, I have tried the following:

Completely removing the server from the domain and giving it a direct connection to the Internet (tried two different gateways also)

Tried changing the NIC settings to not use large packets

I don't have any firewall turned on

I have turned off proxy settings in Internet Explorer

I have run the Update Readiness Tool (it installed a hotfix and that was it)

I have re-registered various WU DLLs

I have downloaded AutoPatcher but it crashes when I run it (because it won't work with Server 2008 I believe

Does anyone have any other suggestions?

Many thanks

Hi

Thanks for your reply. I have just tried turning off Virus scanning and got the same result

Hope NIC points to DNS and not WSUS ?
What if you manually go to update.microsoft.com and try to download the updates and then install ?
Do you have any Proxy on the Browser ?
Is the Firewall turned On or Off ?

Hi

Thanks for your reply. The NIC does point to our DNS server. Going to update.microsoft.com tells me to use my start button to update Windows.

The firewall is off. We use a proxy but I have taken it off the domain and given it direct access to the Internet (also unticked proxy settings in IE when doing this). Tried two different gateways also.

I have already tried changing the large sends settings with no effect.

Just in case anyone else has come across this problem and has arrived here, we have also turned of WSUS in Active Directory.

EVERY server is now saying it has updates ready to download (which was expected) but Windows Update on my computer still won't work! I get the exact same error message.

please share the windowsupdate.log under C:\windows folder.
