Windows 2019 Server RDS stops working after a warning event of DWMNIT. Until the server restarts, the RDP does not work. We did try to restrict the RDP display via Group Policy, but still, we are encountering the issue. Any technical advice would be great.

    Hi Mallesh,

    Do you mean you applied the Desktop RDP settings color depth etc? Follow this link -

    Kind of similar issue but within Citrix this was very frequent on our servers -

    Hope this helps.
