RemoteApp Random Chronic Disconnects

Thank you for your attention.

Problem:  We have roughly 20 users at a remote location using Remote Desktop.  Throughout the day, not everyday and not the same time of day, the users' session disconnects.  The disconnection is brief and most often reconnects without user intervention.  Users are wired and wireless and happens to both groups.

Environment:

We have two locations connected by point-to-point VPN with SonicWALLs.

Location 1 (HQ)
Edge: SonicWALL NSA 250M w/HA - Has redundant ISPs
Core/Access: (2) Cisco 3750X Stack-IP Base
Terminal Server: HP Proliant DL 380 Gen 7, Windows 2008 R2 running the Hyper-V Role, with another Windows 2008 R2 running Terminal Server.  The host OS is running one, small, line of business app.  The physical server has four network ports with two network teams (recently added to resolve issue).  Team one is assigned to the physical server, and team two to the VM.

Location 2 (Remote)
Edge: SonicWALL NSA 220 w/HA - Has redundant ISPs
Core/Access: (2) HP V1910-48G (non-stacked)

I have taken packet captures from switch and edge devices on both ends but haven't found any smoking guns.  We have setup a test user in the HQ location with an RDP session and no disconnects.

Any and all assistance and ideas are greatly appreciated.

Hi what is speed of your VPN ?

Did you have some dedicated speed for RDP and VPN ?

We have same configuration but dedicated speed for RDP users and have no problems more.

I don't know the speed of the VPN, how would I measure this?  We have no QoS in place for RDP.  I would like to know more on setting these up though.

VPN speed is same as your uplink on both sites the less one. But without QoS you can't gar anted speed. Sometimes just simple user use all traffic. And check if you have most recent firmware on network devices.

Issues still going on.  I believe part of the issue was related to routing.  Still working through it.
