Dear Lewis,

Per your second point, Michael, how do you propose setting the host ID
correctly such that a single address is associated with it? In my
experience, having two non-teamed NICs connected to the same subnet has
resulted in a tons of dropped packets and overall poor communication,
aside from the probable packet storm from other clients trying to reach
one interface and hitting the other.
    

As I said in my first post: They are never connected at the same time -
they are just configured (until XWLAN is running).

When I later switch from LAN to WLAN interface I pull out the LAN cable,
and turn on WLAN using XWLAN. Then the requester still works - even a
domain logon. (TCPBEUI is configured for both interfaces)

  

From the Help file:

   This script is executed after the TCP/IP interface has been either
   configured or unconfigured.

I use XWLAN 2.14 and when I turn on the WLAN it does:
1) Turns on the card
2) Searchs for a WLAN
3) Connects to the WLAN
4) Does run xwlan.cmd
5) Configures the IP interface
