Remote desktop connection taking longer than 20 seconds to connect

  • 772

When connecting to one of my servers with remote desktop it takes an unusually long time to present me a log in box. After connecting server is very responsive so it doesn't seem like it is running low on resources.

  • It only happens on this one server.
  • Server is running Windows Server 2008r2
  • The server is one of multiple hosted on a hyper-v box.
  • Hyper-V manager shows that disk usage and memory usage is low.

What might be causing this delay?

windows-server-2008-r2

  1. Turns out it was a DNS issue; trying 3 IPv6 addresses that wouldn't connect before trying a working IPv4 address.

    Sorry all!

  2. Is the 2008 R2 server isolated from the internet? Most likely it's attempting to update its root certificates and timing out.

    Try the following

    1. Launch Computer Configuration
    2. Go to Policies
    3. Open Administrative Templates
    4. Expand System
    5. Explore Internet Communication Settings

    Change the setting of "Turn off Automatic Root Certificates Update" to enabled

  3. You can enable user logon logging by following the instructions in KB221833.

    That will create a log file in %Systemroot%\debug\UserMode which will contains timing information about each step of the logging process.
