@jensens Since you fixed some Windows stuff recently, could you look at this?

For the second part, does the next comment help?
zopefoundation/ZEO#163 (comment)
Running buildout should have created a bin/zeoserver (or maybe bin/zeo) script. Maybe .exe behind it, or something like that. Can you try running that command instead?
