I do the IT work for a local small business. A few months ago the owner decided to change from one software vendor to another. The previous was a web based application and the new one is accessed through Remote Desktop/Remote Access to a Windows 2008 R2 server. All of our desktops run the latest up-to-date versions of Windows 10, all are HP computers, all get about 50mbps down and 20mbps up. We went live with the system on the first of the month however since the beginning our client desktops will experience odd session hanging/freezing seemingly randomly. I will bring up another program(Google Chrome, Outlook, etc) for a few minutes and go back and it will be "frozen". Although this is inconsistent as I can do the same thing for longer and it won't hang/freeze. When this happens I'll kill the app in task manager. Then I go through the log in process again and it brings up the session just how it was before it "froze" saying something along the lines of "Are you sure you want to restart the connection" with yes and no options. I'll then hit no to continue the previous session and it is like it never happened. This only takes a minute but this happens 10-20 times a day for each of my users and they are getting frustrated.
The vendor says they are working to find a solution and that our problem is unique, however it has been a few weeks and they haven't really said much outside of normal troubleshooting efforts. I cannot do anything server side, that's on them, but on the client side I've tried just about everything I could think of or find. I've tried turning off/on just about every MSTSC setting there is, I've updated all drivers for everything(was specifically targeting network and graphics), I've disabled auto-tuning on the NIC, I've edited the registry to only only allow TCP connections in TS, I've reset our router, and I've tried other remote desktop apps. When we went live and noticed it happening we immediately did a Ping Monitor on one of our hosts for a week and ruled out network/internet issues. I've also remoted in to the server from a Windows 8 laptop from home and the issue was not present. Event viewer show nothing anywhere, it's like it isn't happening even though it is.
If anyone has any tips or suggestions, I'm open to anything at this point. If not I'll wait around for the vendor to hopefully figure it out.
