Question : the local device name is already in use problem over cisco IPsec vpn

I have a couple people that dial up with a verizon broadband card and remote access vpn through ipsec with our asa 5505.  I have it setup so that the dns address of our local dns get pushed down to the client when they connect. they have one mapped drive to
net use /delete * /y
net use z: \\intenna-dc1\intenna
and works fine when u are in office with the laptops.  When you are outside, how do i get the asa to push the login script from AD? is it possible?
Also the problem, we been having is when after being connected in office the mapped drive, they go out on different connection and VPN and they get "the local device name is already in use".  now i looked up the error and it says to dissconnect and reconnect. and thats ok but i cant tell a user that. so i was thinking of a solution as to pushing the login script throuigh VPN? any other ideas?

Answer : the local device name is already in use problem over cisco IPsec vpn

if the computers are indeed domain computers then they will run the "computer configuration" section of the applicable GPOs when they start, and the "user configuration" section of the applicable GPOs when they log in.  Only they will run the most recent version that they were updated with while they were attached.

I think fixing the "net use z: /d" section of the code should work.  Let me know if it doesn't and what the results are.
