Windows Live Mail 2011 Doesn't work

Greetings,

 

When I try to send or receive email in Windows Live Mail 2011, I get the following error message:

 

Unable to send or receive messages for the Hotmail.ca account.

Server Error: 0x80048849
Server: 'http://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x80048849

 

However, if I turn the "Smart Firewall" off, I am then able to send and receive mail.

 

How can I get Windows Live Mail to work through NIS?

 

Thanks,

Shane.
