Hello!
Several days ago I installed latest security hot fixes from MS for my Windows XP Prof. After that when I try launch JBossCache for any replication stage (AsyncUnitTestCase.java example) I get UDP exception. Besides local version (I mean w/o replication facility) of the cache works perfect.
I don't have any turned on firewalls (neither MS built-in nor third vendors).
If you have some ideas what's wrong please take me a hint (I suppose that the same code works fine almost week ago).

The valid ipv4 multicast address is
224.0.0.0 - 239.255.255.255
So I don't know why your 192.168.1.168 would work in the first place? :-)
