mstsc credSSP error and client reg fix

CredSSP and mstsc authentication gives some error sometimes, after installing some needed updates, but e.g. youir server is not yet up to date.

You can set back a reg entry… this one:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters]
"AllowEncryptionOracle"=dword:00000002

On the client, save it to a file with .reg extension, as tekst, and double click add to registry, you may need some rights for this.

You can now use mstsc again to your unpatched server, for a while.

Hope this helps.
