I have a Windows 7 PC which connects to remote desktop to the ultrabook. That one has Windows 8.

This works well and never had any problem up to recently.

The problem is when the PC connects with VPN to a foreign network, this makes the remote desktop connection I have to break randomly. It tries several times to reconnect, works for while and then try to connect again.

Anyone would know what updates recently might be in case here or what update I should look at to install?
