Site A-Running Windows 2003 server sp1 terminal services behind a Sonicwall Pro 200 firewall and T1 connection.
Site B-Running Windows XP Sp2 behind a linksys router and using Sonicwall Global VPN Client and remote desktop and cable connection.
Users at site b are constantly losing their connection to the terminal server. We check the VPN connection and it appears to be connected but we are unable to re-connect to the terminal server. Have to disable and re-enable the vpn connection in order to connect back to the terminal server. This happens multiple times daily.
We have checked all time-out settings in the sonicwall configurations, disabled DeadPeerDetection,lowered client resolution, updated the workstations registry as per MS(xp sp2 caused problems with NAT),tried using the connection without the linksys,etc
Any ideas??
