I just installed a MPLS connection between my two offices each with a private network with different subnets. Previously I had a VPN setup to connect the two networks. Each network is bridged by a managed switch furnished by Telcom which translates the different subnets between the two offices.
Traffic is transfering perfectly with all of my Windows XP workstations on both sides of the network. XP workstations are pingable and and network discovery works. My only problem is the one and only Windows 7 workstation and Windows 2003 server R2 on one side of the network can not ping or browse the other network. They worked before with the VPN.
It seem as if that would be a security setup issue with Windows 7 and Windows Server 2003 R2. Where do I start? How do I troublshoot?
