Receiving Error When Attempting to Add User | SBS 2011

Hello All-

On a clients system when I went to create a user, I received two cryptic errors within the SBS console (Unexpected Error & MessageManagement).

When I dug down into the adduser log, I came across this error:

Connecting to remote server servername failed with the following error message : The WinRM client cannot process the request. The WinRM client tried to use Negotiate authentication mechanism, but the destination computer (SERVERNAME:80) returned an 'access denied' error. Change the configuration to allow Negotiate authentication mechanism to be used or specify one of the authentication mechanisms supported by the server. To use Kerberos, specify the local computer name as the remote destination. Also verify that the client computer and the destination computer are joined to a domain. To use Basic, specify the local computer name as the remote destination, specify Basic authentication and provide user name and password. Possible authentication mechanisms reported by server: For more information, see the about_Remote_Troubleshooting Help topic.

I did some searching online and came across two articles that were not much help as all checked out on this server.

This error does not seem to be affecting anything except the creation of users in the SBS console, when it gets to the creation of the exchange account. Nothing to my knowledge has changed on the server, with the exception of a few group policies and group membership changes.

System is SBS 2011, all up-to-date.

Let me know if you have any further questions.
