Just rebuilt my WSUS Server 2012 R2 x64 from a VLSC disc. Added drivers and then joined the server to the domain. I then tried to install WSUS. I was able to add the feature. Then during post install I get the following error:
2017-09-08 14:25:20 CreateDefaultSubscription failed. Exception: System.InvalidOperationException: Client found response content type of 'text/html; charset=utf-8', but expected 'text/xml'. CS0016: Complier error: C:\Windows\Microsoft .NET\Framework64\Temporary ASP.NET Files\apiremoting30\asdv832.dll -- 503 Access denied
Is there something in my GPO that is preventing an account from accessing this directory? This directory has not been specified anywhere in my GPOs but it immediately failed when on my domain. When the server is off the network it installs WSUS without a problem. How can I check?
