I love mRemote.  Makes keeping track of all the different connections (RDP, VNC, SSH, etc.) a breeze.  However, I’ve recently noticed that after I installed Cisco’s AnyConnect client I could no longer open my existing connections or create new connections.  Upon startup I would receive the following window:

What I ended up having to do is remove AnyConnect and then disable FIPS encryption following this link http://support.microsoft.com/kb/811770.

Works like a charm now.  More than likely you don’t have to remove AnyConnect, however I don’t use it that much and rather just remove it all together.

PS: The mRemote project is dead at version 1.5, there’s a fork out there called mRemoteNG which I’m trying out check it out here http://www.mremoteng.org/.
