Thursday, April 2, 2020 9:39 AM
Hi all,
I'm encountering strange issue when I'm using Windows 10 built-in VPN.
Setup:
Client:
OS: Windows 10 Enterprise, 1909.
VPN setup: PPTP, MS CHAP v2 enabled, AssumeUDPEncapsulationContextOnSendRule registry set.
RDP Client: MSTSC, RDCMan v2.7
Server:
Windows Server 2012 R2 VM in Azure.
in Group policy, RDP via TCP is allowed.
Issue:
- Blank Screen after providing credentials.
- when i dont use VPN, i am able to connect to the server and i can see that there is RDP connection event in event viewer.
- No blank screen issue with AWS VM (Windows Server 2016).
another issue when connected via VPN:
- Unable to load certain websites.
e.g. https://community.spiceworks.com/
2. unable to load different API of the same website, for example:
rabbit MQ API:
/api/overview OK.
/api/nodes failed.
same issue when using IP address.
I tried all the above using Android 9 and Ubuntu 18.04 LTS, and all are working.

Hi,
thanks for all the suggestion.
After I adjusted the MTU of the VPN connection, to 1372, there is no more issue with loading websites and RDP to Azure VM.

The Solution(s)
While logged in and stuck on the black screen of death
Press CTRL+ALT+END, or CTRL+ALT+FN+END on laptops. This calls Task Manager and in most cases you’ll immediately see the Desktop.
If only Task Manager but no Desktop appears try running Explorer from Task Manager: File > New Task > Explorer.exe
Try connecting at a different resolution.
Access the remote computers Computer Management or Services MMC and cycle the Virtual Desktop Services.
Update display drivers, both on the connecting machine and on the machine you are connecting too.
Some users are experiencing this with Nvidia GPUs. The Geforce Experience program has a "Share" feature aka "shadow play"; when enabled some people experience the problem. Try to disable it, restart and see if it helps.
Check the display settings at the remote host and see if there is a phantom monitor present. Might need to change which monitor is the primary one
Start a new RDP client on your desktop but BEFORE you click CONNECT, click the SHOW OPTIONS link, click the DISPLAY tab and set the DISPLAY CONFIGURATION to a low resolution like 640×480.
Try turning off Fast Startup
This feature only works when you do a SHUTDOWN and then Boot. It doesn't effect a RESTART.
Go to Control panel, Power Options and select Choose What the Power Buttons Do on the left.
Then select Change Settings That are Currently Unavailable near the top center of screen...
Lower down on the window, uncheck Fast Startup.
Prevention
Disable bitmap caching for your RDP connections
Confirm RDP account has full administrative rights on remote system
Access the remote computer using consistent resolution – Full screen may help
Confirm both systems' video drivers are up to date
