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I have not been able to update this server for a long time, but it is very out of date and really should be patched.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