Vista - WCF Problems

Hell,

I wonder if anybody experienced the following problems that I have all the
time working with WCF Jan CTP.
I use Addressing sample but I experience the same behavior for all CTP
programs and samples.

1. If, on the client, I specify endpoint address using localhost or computer
name (with or without domain) it never works. If, however, I use IP, it
works fine. I troubleshooted my DNS and found no problems whatsoever.

2. If, on the client, I specify endpoint address using localhost or computer
name (see above) and it doesn't work, the SERVICE process enters some weird
state: It starts consuming 99% of CPU time and the process cannot be killed
by anything (neither task manager nor kill utility from Resource Kit). Also
it is impossible to close any of the TCP connections that service continue
to listen to.

I would appreciate any feedback on this.
