Windows Server 2016 (v 1607) VM on Hyper-V 2016 - 1 second lag when typing in console RRS feed

  • Question

  • hi

    I have a Hyper-V cluster running Server 2016 Datacenter version 1607

    This cluster is runnng multiple VMs, including 6 RDS Host servers for users to access both internally and externally through RDGateway. Everything has been running fine since last Summer, but in the last could of days, one of the 6 RDS hosts has started to experience a typing lag. This lag occurs whether you connect via an RDP connection or even if you connect via a console session in Hyper-V Manager (without running an Enhanced session)

    The lag only occurs after you log in - i.e. at the username/password field, typing appears instantly, but as soon as the users desktop appears, anything you type (notepad, word, etc, Start Menu-> Run), any typing appears on the screen very lowly, one character every (roughly) 1 second, no matter how fast you typed in. no characters are lost though.

    This occurs whether you log on as a domain user or a local administrator.

    All 6 RDS hosts are in the same OU and have the same GPOs applied.

    No relevant changes have occurred, and no windows updates have been applied in the last month.

    All other VMs and the host servers typing is normal. Only this one RDS Host.

    Has anyone seen anything similar before?

    Anyone got a fix?
