Upon connect to a remote machine I can across the following error. Since deploying Server 2008 I have seen this issue a few times so I thought I would blog it.
When connecting to a remote machine some clients (usually clients with a new version of the Remote Desktop client on their machine) the following error is received:
The first thing to check is the remote machines certificate. So from a client that can connect or directly on the console do the following:
- Start > Run > mmc.exe
- File > Add/Remove Snap-in…
- Certificates > Add > Computer Account > Local Computer > Finish
- Remote Desktop > Certificates
- Check the certificate expiration date. If the date has past or the certificate is invalid simple right click and delete the certificate
- From a client that was failing to connect try and connect again. Upon the reconnection attempt the remote machine with auto generate a new certificate
Should you still have problems ensure the client settings for remote desktop connection are set to “Warn Me” or “Connect and don’t warn me” under Advanced and Server Authentication. Also check for clock drift (both time and date) between the client and remote computer, anything more than a few minutes can cause problems.
Happy troubleshooting! 🙂
