It's rare that the shell hangs like that, unless it's stuck waiting for a
subshell that died in a strange way.

From the bash shell, did you just run zsh as a subshell or did you try
running it as a login shell (eg: zsh -l)?  As another experiment, could
you enable the rlogin service ('login' in /etc/inetd.conf) and then start
inetd and try using rlogin to see if zsh hangs there as well?  You'll
need to install the inetutils package, run 'inetd --install-as-service',
then 'net start inetd', then try rlogin from another machine.  I'd like
to narrow it down to either a problem with ssh interaction or perhaps a
problem with the system/user profiles in /etc/z* or your local .z*
profiles.

Also, be advised that as of zsh-4.2.4, /etc/zprofile has been updated to
parallel the base /etc/profile.  The update would only apply, however, if
you did not have a previous, custom, zprofile.   A copy of the updated
zprofile is in /usr/share/doc/zsh-4.2.4/StartupFiles/etc

I'll see if I can reproduce your setup, though I only have W2K and not XP
(well, that's not quite true... I *could* setup an XP instance, but I
probably *won't* :).  Is there anything special with your sshd setup?
Did you customize anything?  Is the service run under 'SYSTEM' or under
your userid?

Wait... your using a domain account aren't you?  Hmm... That might
complicate things.  Are you logging in to your domain account via ssh or
into a local machine account?
