I have Windows live on Windows 8.1 Preview.   Frequently but not with any regularity my system will not be able to get a response from the Domain Name Server.   When this occurs it is always after I have used Windows Live Mail.   It doesn't matter if mail is still open or not.   It has never happened with any other app.   I can reach my router and I can ping to an outside IP address but not get to a "Name" address.   I solve the hang by rebooting the router or release and reconnect.    Another machine going through the same router while the above hang is happening cannot hit the DNS either.   Other machines on the same router use different mail apps and do not have problems.
Mail has SSL2 and SSL3 checked.   I have tried with different DNS servers.
Any ideas?
