RemoteApp Random Chronic Disconnects
Posted on 2014-02-24
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.
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.
