I am having some trouble with some Vista machines and now a couple of Windows 7 installations when Network Connect is being used. This is with a SA2000 running 6.3R2.
When the network connect module connects the network in the tunnel is slowed down 10 fold. For example if I ping a node inside the NC tunnel I am seeing 500ms response times, outside of the tunnel I am seeing about 50ms. After much investigating I found that in all cases if after the NC module connects I restart the Windows "Base Filtering Engine" service the response time immediately drops to normal.
One PC was running Vista and had the problem and was upgraded to Windows 7 this made no difference. However, another was running Vista with no such problems but then upgraded the OS to Wndows 7 and is now exhibiting the same behaviour.
Any suggestions would be greatly appreciated.
