Hi Farid
Thanks for posting here.
If a firewall (windows firewall or any other) is running, it may be
blocking multicast traffic which is preventing discovery of members.
(The view change log shows only one member (self) in each process and
not both).
If this is the case, can you try turning off the firewall and report back?
If there is no firewall running and you still see this problem, check if
multicast is enabled on your machine. You can download the resource kit
available here

and use the mcast.exe utility to see if multicast is indeed working on
your machine. Although the resource kit is for windows 2003, it should
also work for xp.
Lastly, check this FAQ entry in GlassFish Wiki :
