I have a small business customer that we just moved to a new building. Other than a new firewall the network is the same.
On one XP pro PC one of the mapped drives works fine if you reboot and keep the folder open, but if you close the folder he is unable to access it after about five minutes of it being closed. Also the computer hangs for a very long time when you try to open the drive after the initial reboot.
The path works for the other 10 people on the network, it doesn't seem to be an issue with the network card.
Any ideas, this has got me stumped.
