XDMCP on notebook with docking station

[Stefan Rupp]

Aloha!

When trying to run XWin.exe on my notebook to connect via XDMCP to
any XDM server in the LAN, I have no problems as long as the notebook
is connected via it's Xircom PCMCIA card.  But as soon as I plug
it into the docking station, the other builtin NIC (3Com 905C
compatible) is used and the same command line does not work any
longer - no connection is established.  To drill the problem
down I used the -from <local-ip-address> option and suddenly it
worked.

Apparently XWin.exe tries to connect via the unused Xircom PCMCIA
NIC, even if the notebook uses the other NIC.  Since I receive
my IP adress via DHCP, the above solution will not work generally,
due to the fact that the IP number changes each time I log on,
so I need to edit the command line.

Is there a solution to this problem, which enables me to
connect via the correct interface, whether the notebook is
using the PCMCIA or the builtin NIC without the need to change
the startxwin.bat each time I log in?

Thanks in advance!
