strange problem. client has two servers. one server has several mappings to workstations via login scripts. a workstation with Vista at times during the day will attempt to explore the contents of a mapped drive or save a document to the drive, and gets an 'invalid handle' error on the drive. the other drives remain connected. when i browse the network with the workstation i can get to the server\vol\folder location without error. but only in the following format:

\\tree_name\.server_name_vol.ou_name\folder_name

it is very reminiscent of the days of having two login scripts for NT and 98.

the login script works without error. only breaks later on after login. any ideas?

thanks
