RDS / Outlook interactions causing crashes?
-
I am currently dealing with an issue where a remote office runs their ERP system on their desktops via an RDP connection back to the hosting server at the main office. When a user at the remote office has a local install of Outlook open as well as their RDP session, and they decide to click from the RDP session aplication to Outlook, the RDP session frequently crashes. This could be happening with other open local applications, but Outlook is the only one that I have heard specifically named as an issue.
The remote office is connected by a site-to-site VPN to the main office, with an Edge Router at each end of the pipe. We are seeing pings ranging from 60ms to over 200ms, with an occasional timeout, and the average is about 100-120ms. I'm not sure if this latency has anything to do with a local app causing an RDP session to drop, but I'm curious what the community has to say about this.
Have you seen this happen, or something similar? What was the root issue?
-
Quite odd, I have not experienced that before.
-
Sounds odd that one, what about testing and disabling local resources on the RDP client to see if there is any local interference? (i.e audio) might be a worthwhile test? also could try reducing the screen resolution?

I feel like part of the story is missing. Do you have any logs to prove this?

Logs to prove what? That the RDS session is dropping out?

So no errors just a dropped connection? That doesn't make sense

How far away is the main site from the satellite office?

One is in Rural DownState NY the other is in NC.

What are the system specs of the workstations they are using as well as the network equipment installed? 200ms seems high for ny state to north carolina. I have a friend who lives in raleigh (I live in NJ) and we have much less than even 75ms if I try to remote to one of his servers.
My last company had a similar setup. 33 sites remoting to a single terminal server at the main site to access network resources.

Keep in mind that the main office is more or less in a corn field, 5 miles outside a dinky town, and the only cellphone service there is via the wifi in the building. The ISP is the local phone company. On the other side, the location is outside a small city area, but at least on a road with a couple other businesses nearby. I'm getting those pings from a server at the main location pinging the router at the remote location. It's not always that bad, but we see it more than occasionally in that range.

That is a really rough situation. Did you try to RDP into it from your own computer? Can you maintain a connection? Could be the ISP. Could also be a lack of memory to run all of that on the local workstations.

The RDS server has these that seem likely to correspond to the drops:
Windowss logs/System:A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 10. The Windows SChannel error state is 1203.

That's a security check issue.

LOL nice.

Frankly I was thinking there might be something in the Client side log showing RDP was crashing - but now that Gene's found RDS Server side errors - he has something to go on.
I'm guessing that some kind of data is trying to come back across the RDS session to the RDS server, but time will tell.

Whoops.. I thought Gene started this thread - OK you just made Scott's point about some kind of tag that shows who the OP is
