You're right!!!(duh). I have Wingate client installed on my PC which is an app trying to fool my other PC apps that there is no firewall (there is a Wingate Server .. Acting as a firewall) Bottom line .. When I disabled the Wingate client all worked 100%.

Is that the case or not? If you do have firewall/VNC software installed, I can assure you that it most likely IS the problem; the fact that other software works fine has no bearing on whether or not Cygwin/XFree86 will work fine. You see, Cygwin/XFree86 is heavily dependent upon TCP/IP working exactly correctly. Remember, we are not just using the Win32 API for TCP/IP... we are using Cygwin to emulate the POSIX/UNIX interface to TCP/IP using the Win32 API TCP/IP calls. This requires taking advantage of some peculiarities of the Win32 API TCP/IP interface. Can you assure us that your firewall/VNC vendor implemented each and every one of those peculiarities correctly? If not, then we just have to assume that the firewall/VNC software is the problem. We have dealt with this issue several times in the past and the correlation between Cygwin/XFree86 not working and firewall/VNC software being the blame is about 100% in cases where firewall/VNC software was ever installed on the machine. Yeah, that's another little bit about the firewall/VNC software: some of the vendors are sloppy and their uninstall routines do not replace the original Win32 API TCP/IP DLLs... they just leave their own in place. We have had people that have uninstalled firewall/VNC software and still could not get Cygwin/XFree86 to work. Then they reinstalled Windows and Cygwin/XFree86 worked. As a final test they reinstalled the firewall/VNC software and Cygwin/XFree86 broke. They uninstalled the firewall/VNC software and Cygwin/XFree86 was still broken. That was all in the mailing list archives, but I felt like writing about it for some reason. Hope that helps, Harold P.S. Oh yeah, and if you have never installed firewall/VNC software on your Windows machine, then kindly disregard the above. :)
