Question : Exchange 2010 "RBAC" error in event log

I keep getting the following error in the application log of the event viewer on my exchange 2010 servers.  I can't seem to find much information about it and how to fix it.  Below is the error:

Source:  MSExchange Configuration Cmdlet - Management Shell
Event id:  17

(Process w3wp.exe, PID 4808) "RBAC authorization returns Access Denied for user . Reason: No role assignments associated with the specified user were found on Domain Controller server1.domain.com"

Does anyone have any idea what would cause this error.  If so are there any solutions?  I can't seem to find one.  Thanks.

By default vista and win7 allow only administrator to install print drivers, i think you are trying to install through local user ?
If yes , follow below steps to do manually

Login as local user --> control pannel--> double click printers--> then run as administrator (Alt+right clik choose run as admin) --> Add local printer--> create new port , for type choose local port -->enter port name (adress :- //ip adress/sharename of printer ) --> next --> finish
