I was talking to Methos on NecessaryEvil this morning and he suggested that the problem might be with cygwin. MS Windows users normally use the helper library cygwindevo.dll that came bundled with their zipped teknap file and resides in the primary TekNap folder (C:\TekNap where you also would find teknap.exe.)
I don't know who compiled the original dll, but a full installation of a Cygwin environment might solve this issue. If you care to test this on a Vista machine, please post the results here.
An article on installing Cygwin on Vista is
here at sysdigg.blogspot.com. There is an SSH version of Cygwin around.
