Hi,
I have a Wwndows server 2008 R2 Enterprise server on which I am not able to install any hotfix(.msu) extention its giving me an unknown error CODE 80070643 even when I try to check for updates through windows update, it is asking to install the latest update for windows update. But when I install the update it gives me the same error code. I have even changed my web proxywith full access, but still I am facing the same issue. I am getting following error in my event logs-
