Could not open netlogon batch file from UNC

I kept getting this, which was driving me crazy:

windows cannot access the specified device, path, or file”

Turns out, that although I was referencing a UNC, that the IE7 advanced security settings were bunging it all up. I could view the share contents (.bat file) on the local computer but not remotely.

So, to resolve, went into Add/Remove Windows components and pulled the *delightful* IE7 security enhancements off my server.
