I have three users now who are having problems with drive mappings on their XP machines. All are XP Pro SP1, are attached to our domain, and log in as domain users. They have drives that are mapped via a logon script every time they log in. Sometime during the course of the day, one or more of their drive mappings "disappear." When I say "disappear" i mean that there is no trace of the network drive mapping anymore - it does not show up in explorer, it does not show up in the list of mapped drives when you select "Disconnect mapped drives" - it simply just disappears. Most often the drive that disappears is their Home drive (we map their home drives to h:) but other drive mappings have been known to disappear. Has onyone seen this behavior, and if so how was it resolved?
