Re: Can't connect with XDMCP - Invalid MIT-MAGIC-COOKIE-1 key

Alexander [Skwar],

Wait, let me get this straight.  You DO have two network cards, one in 
the notebook and one in the docking station, right?  Now, are you sure 
that you are using the same network card on both network segments?  That 
is, are you using the built-in network card on both segments and you are 
never using the docking station's network card?  If that is the case, 
then I suspect that you problem is when you are plugged into the docking 
station and XWin.exe thinks that it should use the docking station's 
NIC, which does not have an IP address (thus the 0.0.0.0).

The easiest solution would be to use the -from parameter.

Other possible solutions:

1) Plug into the network at the docking station via the docking 
station's NIC.  XWin.exe wants to use that NIC by default, so XWin.exe 
will work correctly without the -from parameter (probably).

2) Disable the docking station's NIC in your Windows hardware 
configuration.  This will hopefully case XWin.exe to not even see the 
docking station's NIC as an option.

3) Change the binding order or NIC preference (if there even is such a 
thing) in your Windows hardware configuration.  I am going out on a limb 
here... I do not remember if this can be done.

4) Stop using your docking station.

5) See if Alexander Gottwald has any ideas to save the day :)
