[plt-scheme] Re: Can't get the web-server going

Just a hunch, but I suspect Windows is not letting you "listen" no  
matter what port number you specify.  You can try going back to the  
default configuration (temporarily) and using different port numbers  
like this:

$PLTHOME/bin/web-server -p PORT_NUMBER

Meanwhile I'll copy my PLT web from Mac OS X to Windows XP and see if  
Windows adds any barriers.

Hmm, that message, (my caps) "AN ADDRESS incompatible with the  
requested protocol" makes me wonder what address the system call is  
seeing.  I googled that string and saw you are not alone in your  
Windows woes.  See:


This page:  http://www.techspot.com/vb/topic16323.html
offered this advice:  Netsh winsock reset; reboot; reinstall TCP/IP  
Also: http://www.computing.net/windowsxp/wwwboard/forum/118679.html

The above are related to Windows Firewall, detecting/disabling  
spyware.  Good luck.
