Fetch uses a different site for detailed info then the two day forcast info!
When I was adding error catches I tested with incorrect city codes.
In the next release I'll change the message box to reflect that it is a connection problem!
It isn't trying to access threw dial-up unless you have Windows configured to do that!
Since you can connect with one XP machine but not the other the issue is the PCs configuration.
Is Windows firewall running on that one and not the other?
If it is running on both make sure the settings are the same.
You'll need to do some digging to find the differences on each PC.
Use the task manager to compare what is running on each machine.
Use Msconfig to shut down services and programs that run on start up.
Check to make sure any identical programs that are running have the same settings configured
