This is a really goofy problem. I have 3 domains at different sites and 3 RDS servers. All servers are 2012 R2. Users from all 3 domains log into the RDS servers at other sites for various applications, using credentials for the appropriate domain.
If domain1\user logs into the RDS server at domain 1, 2, or 3 printer redirection works as expected. However if a domain2 or domain3\user logs into the RDS server at domain1, the printer is redirected BUT it has the wrong name so it looks like someone else's printer. If you right click on the device in Printers and Devices and look at the printer properties you will see the correct name. This makes it very confusing for users and generates lots of support calls.
Notes: At domain 2 and 3, I allow the redirected printer to be set as the default printer. At domain 1 I do not, they must manually select their default printer (to prevent accountants from printing large reports to their check printer).
At domain 1, if I add a user to the Print Operators group, the correct printer name appears.
?????? Any suggestions about troubleshooting this issue is appreciated.
