How to fix RDP for Windows Server 2025 's lag & always disconnect

Hello Dang,

Thank you for posting question on Microsoft Windows Forum!

Based on your query of fixing RDP for Windows Server 2025 's lag & always disconnect. Well! Frequent RDP lag and disconnects on Windows 11 Pro are probably linked to recent updates (especially version 24H2), network policies, or misconfigured client settings.

Since you are on Windows 11 Pro, you have access to some "under-the-hood" settings that can usually iron this out. The following are some suggestions you can try in an attempt to fix this issue.

• Before you connect, click Show Options in the Remote Desktop Connection window. The default settings are highly likely too "heavy" for less-than-perfect connections. On Experience Tab: Change the performance dropdown to "Low-speed broadband (256 kbps - 2 Mbps)". This disables visual themes and menu animations that eat up bandwidth. Then on Display Tab: Reduce the color depth from 32-bit to 16-bit. You will not notice much difference for work tasks, but it drastically reduces the data being sent. Finally for Persistent Bitmap Caching: Ensure this is checked. It allows your computer to store images locally so it does not have to re-download the "Start" button icon every time you move your mouse.
• By default, RDP tries to use UDP for speed. However, if your network has even minor packet loss, UDP causes those annoying freezes and disconnects. The suggestion is to Force RDP using TCP instead. On the local (Client) PC. Press Win + R, type gpedit.msc, and hit Enter. Navigate to this path: Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client. Find "Turn Off UDP On Client" and set it to Enabled. Restart your RDP session.
• Windows sometimes tries to be "helpful" by offloading network tasks to your network card, but this might cause lag spikes in RDP. Try to disable offload task. Right-click the Start button and select Device Manager. Expand Network adapters, right-click your adapter (Ethernet or Wi-Fi), and select Properties. Go to the Advanced tab. Find Large Send Offload V2 (IPv4) and set it to Disabled. Do the same for IPv6 if it is there.

Also, the last point to mention here is to check the Physical. If either the host or the client is on Wi-Fi, you are going to see jitter. Try to get at least one side on a hardwired connection or try to use a wired Ethernet connection instead of Wi-Fi for better stability. If using VPN, test RDP without it to rule out VPN-related latency. For Power Settings. Ensure the host PC is not "sleeping" its network adapter to save power.
