User case: How to solve Windows Server 2019 RDP freezes issue?

“Hello!I have a Windows Server 2019 Standard on a Dell Power Edge T440 server. I can connect to it via RDP, but after some connections, it stops working only a black screen appears. When this happens after the server's GUI freezes, the mouse and keyboard do nothing, same from local and from iDrac console. Only a full reboot helps, but every service works this time, only the GUI interface not. Here is no error in iDrac. If I do not connect via RDP only local logins everything works great. What can cause this? I tried the RDP from local network and from VPN, their result is similar.”

Why does remote desktop freezes on Server 2019 occur?

There could be several reasons why Windows Server 2019 RDP freezes occur. Some common causes include:

★ Network connectivity issues: Sometimes, RDP freezes can occur due to network connectivity problems. For instance, if there is high network congestion, it can cause RDP sessions to freeze. Similarly, if there are issues with the network hardware, such as a faulty router or switch, it can cause RDP freezes.
★ Driver issues: Outdated or faulty drivers can cause RDP freezes. For example, if the video driver is outdated or malfunctioning, it can cause the RDP session to freeze.
★ Resource constraints: If the server is running low on resources, such as RAM or CPU, it can cause RDP freezes. This can happen if there are too many active RDP sessions, or if there are other resource-intensive processes running on the server.
★ Security settings: In some cases, the security settings on the server may be too restrictive, causing RDP freezes. For example, if the server is set to block certain types of traffic, it can cause RDP sessions to freeze.
★ Software conflicts: If there are conflicting software applications running on the server, it can cause RDP freezes. For example, if two applications are trying to use the same resources at the same time, it can cause RDP sessions to freeze.
