About this tag
The protocol error tag on WindowsForum.com covers issues related to Remote Desktop Protocol (RDP) mismatches and disconnections, particularly when connecting from Windows 7 to older Windows Server versions like Windows 2000, 2003, and pre-Windows 10/Server 2016 guests. Common causes include outdated mstscax.dll files, integration service version mismatches in Hyper-V, and protocol errors during session shadowing. Discussions focus on troubleshooting steps such as replacing system files, updating integration services, and identifying compatibility problems between client and server RDP implementations.
