Windows Server 2008 R2 Enterprise, 64-bit
So, I work remotely with an IT company, and we have a client terminal server that stops allowing the users' local printers to map occasionally. All of these users are set to map local printers in Active Directory. In the past, I've resolved the issue by disabling and re-enabling the Remote Desktop Device Redirector Bus and restarting the server. This works 100% of the time, but the issue seems to come back again several days later. The client is of the medical variety, so restarting the server isn't always a viable option, such as when this occurs midday. I am wondering if anyone has had experience with this and could give an idea of a root cause and possible permanent solution.
I've found information online about reinstalling the RDPDR.sys file or replacing the RDPDR registry subkey, but I wanted to get some other opinions before I go that route. Some help and/or information would be greatly appreciated!
