I can't reproduce this problem.

Per your cygcheck output the USERDOMAIN is AD1, but the passwd
entry shows U-EMEA\wg.  How does that happen?

Are you sure /etc/passwd is really correct?

What do you mean by "HOSTNAME missing"?  The environment variable?

So your hostname is the same as the username?  Hmm.  I wonder if that's
the problem.  Back in NT4 days it was no problem to create a local
username identical to the hostname but it goes all trouble.  That's why
this is disallowed in Windows 2000 and later, which just refuse to
create such a username.  Of course Windows can't do the same check for
domain accounts.

[...time passes...]

Hmm, no.  I created a domain account using the same username as the name
of one of my XP client machines.  Then I logged in to that machine using
the new account and started the first Cygwin shell:

I have no idea why this happens for you.  Some debugging will be necessary.
Starting the first bash from strace might give a clue.
