XDMCP Problems - Possible fix, please try

[Harold L Hunt II]

The XFree86-xserv-4.3.0-30 release may fix some problems with not 
getting a login screen when using XDMCP.  See the change log for more 
information:

http://xfree86.cygwin.com/devel/server/changelog.html

Please try this new server and report on whether it allows you to get a 
login screen or not.

Thanks for testing,

Harold
