I just migrated from a 2003 terminal server where we were using black ice print2rdp to redirct printers, to a 2008 Terminal server using the standard redirect for printers. What happens is users will log in and one day will get all the redirected printers but a week later they log in and the printers do not redirect. and it is random to whos does not work. Also we replaced all the printers at once to the same brother laserjet at all locations. Print2rdp on the 2003 would fowl up when users disconnected instead of log off, however i removed the connection bar so they can only log off any more (already tried this on the 2008 did not resolve). also logging the user out and back in and rebooting the desktop does not resolve the issue either.
