Office network using Windows Server 2008 and client systems all Windows 7 Pro. One user suddenly cannot map a printer or shared network drive unless he uses the IP address. This presents all sorts of problems for this user because there are no IT or techs on site when he needs to map a printer or drive. Is there a possible solution for this problem? We have rebooted several times, have tried removing and remapping printers and drives but nothing seems to work. Please advise.
