SocketCreateListner() failed

[Sandeep & Prerna Gupta]

Hi, 

I am trying to install Cygwin 6.8.1.0-5 on a Windows XP Home Ed. Version
5.1
cygwin bash shell comes up OK, but startx command fails with 
Fatal server error: 
Cannot establish any listening sockets - 

The log says XWin was started with the following commandline:
X :0 -multiwindow -clipboard

Any ideas on how to fix this? 
Thanks
Sandeep
