Is it possible to have a TFS build activity run on a specific agent?
===

We are using TFS 2010 and we've got a requirement to run a separate EXE to execute our old VB6 build script. We've got 3 build agents spread across 2 machines but only one machine has the VB6 development environment on it (as well as the old build script) so only one agent can do this work. I know how to do this with a build activity in our build template file but because we've got 3 build agents on 2 different machines, my question is how can I make sure this activity only runs on the one build agent which contains the VB6 development environment?

I realize this creates a bottleneck but it's only temporary for now. It would be ideal if I could do this without creating a custom DLL for a custom activity. Also, I understand with tagging I could create a different build definition for this work but again, this is not ideal... I want one build workflow that runs this on the one agents but the rest of the activities afterward continue on their respective build agent(s).
