We have around 20 HTC Touch Pro mobile phones trying to create a VPN to the main office server. The VPN connects ok, and we can ping the server ip address from the phone. The problem is as soon as IE or Opera is opened to connect to the Intranet, the connection is lost.
Obviously the firewalls are ok to the traffic as RRAS is showing the host is active, and the phone can ping the server - until IE tries to connect the the server name or IP Address.
I'm just about at my wits end with this, so any help would be greatly appreciated.
