Recently installed new Windows 7.0 professional edition and now whenever I try to remote desktop it’s throws error like following
An authentication error has occurred.
The requested security package does not exist
so I had to search on google an I found that the problem is due to some missing parameters in the Registry.
Apparently one of the sys admins deployed an sms package that removed some settings from this key:
It should have these values: kerberos msv1_0 schannel wdigest tspkg pku2u
The tskpkg and pku2u values were missing.
After adding them and rebooting and I can RDP to 2008 servers.
