When this happens (pretty rare) I edit the files and make them the way that they should be.
For example, I will delete out the 2nd set of TFS bindings (Global Section(Team Foundation Version Control) or fix any other discrepancies that I see.
In addition the suite contains various administration tools, and a DNS resolver interface library.
The latest version of BIND is BIND 9, first released in 2000.
However, if rebinding doesn't work, you might try editing the solution files directly.
