User on XP. Mapped correct Drive name as it appears in AD. On the Network okay. After mapping we can access it but after a reboot of machine it vanishes and has to be remapped again, the only way I found that works is to create a shortcut on the desktop and that lets me into it but isnt exactly ideal, Just wondering what could be causing this issue with disappearing each day. Have tried adding (Company name).com suffix after the server name to see if this makes any diffence. I checked the permissions and can confirm that the user has full permissions for the given path, Mapped the path myself through my Citrix connection and then logged myself off and reconnected to server but didnt disappear, so makes me think it is a local issue on machine.
