Just back from a trip and tried the fix you suggested, 'rustle', which worked. Thanks for the help.
Now to the next problem. The network will not open (if that’s the right term) unless I turn Zone Alarm off on the primary computer. (I run Zone Alarm 6 on both machines.) Not a huge problem – I can easily disable ZA any time I want to use the second computer, but it would be nice if I could use the network with ZA running.
Any suggestions on how I should configure ZA6 to allow the other computer to gain access to my main computer with ZA running? I also notice that ZA defaults to switching the Windows Firewall off.
