It sounds as if your server is not reading server.properties at all. I'm not as familiar with Windows and servers but see if backing up server.properties and then deleting it, thus allowing it to be regenerated does anything. With the 'newly generated' server.properties try editing that. If it still isn't working make sure you are editing it in the proper format and correctly. If you look at the Minecraft wiki here this gives you some useful information on how it should look etc. Note, however there will be more lines in the Tekkit and they will require different answers.
