Mapped Drive in Domain

I have a couple of Windows XP boxes in my active directory
that have trouble reestablishing their user directory
mapping. Once the user logs on the drive mapping shows red
until you access the share with explorer then everything is
ok. I have two other shares mapped on the computer from
the same server and they work without any problems.

If you open a program and try to access the share before
access the mapping from explorer, you get an invalid drive
error. This drive is the users home directory as mapped
from their account in the directory. m:
\\fileserver\username one other share is g:
\\fileserver\programs. This isn't consistent with all XP
machines only two, one laptop and one desktop other XP
boxes work without any problems. I can't pinpoint any
thing specific to the user accounts that would be causing
this and I've changed the mount point using the FQDN of the
server without any luck.

Why some mapped network drives show a red x

SYMPTOMS: You find that the network drive mapping may be disconnected after
15 minutes of inactivity and Windows Explorer may display a red "X" on the
icon of the mapped drive. However, if you double-click it reconnects
quickly.

RESOLUTION: by default, idle connections will be dropped after 15 minutes.
To modify idle time, at a command prompt using net config server
/autodisconnect: minutes. For example, to set the Autodisconnect value to
30 minutes, you would run the following command line: net config server
/autodisconnect:30. If you would like to turn Autodisconnect off, do net
config server /autodisconnect:-1.
