Hi Rafael

I had exactly the same error.

In my case, it had exactly *nothing* to do with firewall, or Windows problems.

It happened because I **used** X in the administrator account. (I work
on a limited-rights user account, and use the adm account only for
install/updates) When launch X as adm, the administrator takes
ownership of the /tmp/.X11-unix/ directory, which I believe X needs to
access to run.

The solution was just to login as adm and change the ownership:

adm$ cd /tmp
adm$ chown __your_user_name__ .X11-unix

After that, X works well *for that user*, as long as you don't try to
use X as adm again.

(BTW, this is an old issue with Cygwin/X. As a rule of thumb, one
should avoid running it as administrator, unless that's how you want
to keep using it... Unfortunately, Cygwin/X does not have a mainteiner
now, so we don't know how long this "unducumented feature" will still
be around.)
