Guys,

!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!PLEASE HELP!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I have a slight problem and being the idiot I am, i need to get it sorted
before I can
get on with my study. It's a problem with DLSW Lite which i probably wont
even get in
the lab anyway but you know me. Im a sucka for pain!!!!!

I cannot get DLSW lite to work (or cannot get the two win2k PCs to find each
other in
network neighborhood browser).

On the routers, you can see the MACs in the bridge group and using the "show
dlsw reachability"
you can see both the local and remote devices (MAC and Netbios names). I
get transmit and
received packets on the "dlsw peer information and on the bridge group
information)
I even see a circuit being established when I try and mount the other PCs
file system.

What can I be doing wrong here? Spent hours on it now :(

I have tried doing it on a point-to-point FR cct but I can even get the peer
to "connect"
and I am using the correct configuration recommended but on point-to-point,
i get the
following from a debug "event:TIMER-TIMER EXPIRED state:CON_PEND"

- MAN, WHO NEEDS DLSW LITE ANYWAY?

When I do a show bridge on both routers :-

ccie-rtr7#sh bridge
