I have installed an Ifrant Ready/NAS for backups. The problem I'm having is getting Windows XP Pro SP2 to keep the NAS listed in the My Network PlacesMicrosoft Windows Network folder. Sometimes it is there and sometimes not. This is playing havoc with my backup software which won't backup to a mapped drive. I have tried installing the NAS and turning off my Firewall -- makes no difference. If the NAS is seen by XP, and if I run a backup successfully, as soon as the backup is done, the NAS disappears again. A reboot doesn't bring it back. I would appreciate any suggestions.
