I can connect for file transfer,terminal and rdp access with no problems.
The host is windows xp, running 7.6.2.0. It's is a virtual machine.
The viewer is on Windows 11, running 7.6.2.0.
I have recreated the connection in the viewer, it did not help. It stuck on Connecitng to xxxx Please wait. I have tried from a different computer to connect to the host, same problem. The host is set to legacy capture. Any ideas?

Hello Brad,
Have you tried enabling/disabling hardware acceleration on the XP machine and/or 'accelerate 3D graphics' in your VM settings?
100% that the issue has something to do with graphics [drivers/settings].

Thanks for the replay, I'm running it on proxxmox, so none of those options exist, and hardware is set to standard vga. The viewer will connect if I reboot the system, and works fine. It stops working if I rdp into the computer. Once i do that, I can't use the viewer anymore even if i disconnect from the rdp. The only fix is to shutdown the computer and power back on the virtual machine. It works again until i rdp into the system.

Hi Brad,
Just to clarify, do you mean that it's the Full Control and/or View mode works until you rdp into the computer?

Correct. Even after I disconnect I'm unable to use full control and/ or view mode.

Hello Brad,
This issue might arise because of how RDP interacts with the display driver on Windows XP (and older systems in general) within a virtual machine. When you initiate an RDP session, the operating system switches from the standard VGA driver (used by Proxmox) to the RDP-specific display driver. Even after disconnecting the RDP session, the operating system may not switch back to the original display driver.
Possible solutions:
1. Avoid using RDP for that machine altogether (if possible).
2. Limit RDP interference by launching RDP with the /admin or /console key:
3. Force XP to use the original VGA driver (a hack):
Locate the registry entry:
4. Instead of restarting the virtual machine, you can create a bat file to manually make WinXP to switch back to the local console session:
Still all the suggestions above aim to help with the same - switching back from using the rdp driver to the standard driver, which is the possibly the root cause of the issue.
Hope that helps.

mstsc /adminto connect to the console session instead of creating a new RDP session.
3. Force XP to use the original VGA driver (a hack):
Locate the registry entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-TcpFind (or create) the DWORD value:
DisableHardwareAccelerationand set it to 1. Then restart the virtual machine.
4. Instead of restarting the virtual machine, you can create a bat file to manually make WinXP to switch back to the local console session:
Which you will need to run after the RDP session is over.tscon 0 /dest:console
