My network has multiple Point to Point T1's to branches and 2 site to site VPN's to two other branch locations using DSL service at one and at 10 Meg fiber link to the other. Equipment at the datacenter is a cisco asa 5510, at the DSL branch office it uses a CIsco 5505, and at the fiber location is a PIX 515E.
All point to point t1 sites function without issues.
Both VPN branches have ongoing issues when connecting back to the datacenter where servers reside. The first issue is with RDP sessiongs, typically the rdp sessions will last from 30 seconds to a couple of minutes and then they will drop with the typical blinking computers in the upper right corner of the session and will then resume after a couple of seconds pass. Another indicator of traffic issues is that when using outlook 2003 to connect to the exchange server which resides at the datacenter, eventually the 2007 exchange server will throw application events that the user has exceeded maximum number of sessions. When this happes they can no longer open and work in outlook and thus must restart thier machines to get back in. One more bit of information, if I have the users at the VPN branches use the outside IP of the terminal servers, they do not get dropped, they only get dropped when traversing the VPN.
Any thoughts would be greatly appreciated.
Thank you
