Hi everybody,
I have an issue that has been cracking my mind..
A few years ago I configured a server for one of my customers, it's a Server 2008R2 with the RDS server role.
It has been working like a charm for years,,
This is what's going on.. (all of the problems exist while a user is logged-on to a RDP session).
In the AD is a container with a few users that have some extra rights through a GPO.
These users have administrator rights(member of the builtin admin), and rights to start the task-manager to send messages to other users.
All of a sudden these users are no longer able to send messages, they are able to open the taskmanager but a soon as they try to send a message, it says access denied.
The builtin administrator can still send these messages.
I tried creating a new user and the same issue appears.
I checked the date when the last modification have been made on any GPO but the last change was about a year ago.
So nothing changed in the user rights or GPO's.
An other issue that occurs is when a user opens a browser session(IE) and needs to browse the server to (for example) upload a file, it suddenly starts asking for credentials on the shares.
But when the user opens a share through the windows explorer, it works fine.
The browser doesn't start in any special way, just a simple users session.
The event viewer doesn't display any information that has anything to do with these issues.
This all started about 2 weeks ago.
Any ideas?
With kind regards,
Tim Grave
