Today we were troubleshooting a strange behavior in a customer environment. When connecting to several target machines the Remote Desktop Client hung for about 30 seconds at “Securing remote connection”. The issue seemed to be RDP Version related, as connections to Windows XP/2003 machines were established fast – while Vista/2008 or higher showed the issue. 4more derivativesap calculus.

Since a few days RDP takes too long to connect. Securing Remote Connection bar stanys around 20 seconds then it connects. I checked the DNS but all seems good. When the remote desktop connection between a Windows desktop and its host fails, it's time to do some remote desktop troubleshooting by checking firewalls, security certificates and more.

So if your network does allow lookups to external resources, and there are NO good reasons to do so, make sure to reject connections – at least from your own network – instead of dropping them. For maximized security strictly disable external DNS in isolated networks to avoid DNS tunnel attacks.
