Lost drive mappings

[Richard]

I run XP Home on my PC and access a Windows NT server via
a small Lan. I have defined mappings to 3 shared drives
in the server to drive letters F, G, and H. All are
defined with the 'reconnect at logon' option ticked.
All worked fine until I changed the LAN card in my PC to
a 3Com 1Gb card (model 3C2000); whenever I boot the PC
now, these mapped drives are unavailable. If I go into
Windows Explorer I can see the drives under 'my
computer'; the drive letters have an X through them. If
I open 'My Computer' from the Start menu I again can see
the drive letters but they again have an X through them.
If I then double-click on each drive letter in turn, they
open and I can see the contents of each drive, and the X
disappears, and I can use data and apps on these drives
OK (until the next reboot). As far as I can see I am
logging into the server domain/workgroup OK, there are
successful login entries in the event viewer. Other XP
PCs on the same Lan (including those which have had
similar Lan card changes) do not have these problems and
connect to the server drives OK when they boot. Any
ideas what's causing this failure to map the drives ?

Some network drives show with a red 'X'

Symptoms: you have mapped some network drives and checked the reconnect at
logon, or your network uses logon script to map network drives. After
rebooting, some network mapped drives may show with a red 'X'. If you click
on the drive, it becomes active.

Cause: net use /persistent:yes is default settings for NT and win2000/XP.
This is why when you have mapped some network drives and check the reconnect
at logon, or your network uses logon script to map network drives, the
mapped network drives may show red Xs after rebooting. If you enable echo
and pause the logon script or if using net use to map the same drive
manually, you may get "System error 85 has occurred. The local device name
is already in use." One thing you may want to try to avoid the red X is
using net use /persistent:no, for example, net use i: \\servername\folder
/persistent:no.
