Hi,
Recently I have deploy WSUS on Windows Server 2008 R2 64 Bit, I have issue with windows 8 machines as they are not communicating with WSUS server, I have run this hotfix KB2734608, but after that all the systems are getting error code 0x8024401f while updating.
Below is the log file from one of the client machine.
