I have an ASA5510 and am using the Cisco AnyConnect Secure Mobility Client v.3.1.09013. The VPN connection works fine, I can browse network shares, access network resources and RDP or SSH into any server on the corporate LAN except for Windows 2012 R2 servers. The server do respond to a ping over the VPN. When I am in the office on the corporate LAN I can RDP into the Windows 2012 R2 servers without issue. We have a mix of Windows 2003 and Windows 2008 R2 servers along with some Linux machines and they all connect without fail. The behavior is consistent on OS X, Windows 7 and Windows 10. Has anyone else experienced this issue?
