Network Drive reconnect at logon

I set up a couple network drives while connected to my
office's VPN, but I accidentally left the "Reconnect at
logon" box checked. Now, everytime I start up I get an
error message that "the network drives could not be
reconnected" because I haven't logged back in to the VPN
yet. How can I change the list of network drives that
are scheduled to be reconnected at login? I couldn't
find it in the registry. (I also tried re-mapping those
drive letters to a local resource, to no avail.) Thanks
for any advice you can offer!
