About this tag
The vms3cap.sys driver is associated with Hyper-V virtual machine management and can cause blue screen errors on Windows Server systems. In reported cases, crashes occur intermittently when initiating RDP connections to a guest virtual machine running Windows Server 2008R2 on a Windows Server 2012 R2 host with the Hyper-V role.

Troubleshooting typically involves checking for driver updates, reviewing system logs, and verifying Hyper-V integration services.
