This one is pretty annoying. I remember once spending a lot of time on one case before I figured it out.

If you add an entry like to the end of the C:\windows\system32\drivers\etc\services file:

mi-raysatsi2012_3_9_1_44	7024/tcp

where there is no line break after the “tcp”, then the raysat service won’t start and will report “Error 1092”.

But if you add a line break after the “tcp”, or add a # comment like this, then you can start the raysat service:

mi-raysatsi2012_3_9_1_44    7024/tcp        #

Aaaargh.
