sc.exe

I was able to create a service from .exe file only with the bare min. Could
not use any option what soever
eg
sc create mysvcname binpath= mysvcpathname.exe
could not specify type= nor start= nor anything else

I then try to config by
sc config mysvcname start= boot type= interact
and I get
[SC} ChangeServiceConfig Failed 87:

The parameter is incorrect.

Tried
sc config mysvcname start= boot
I got same msg


tried
sc config mysvcname type= interact
I got same msg
and other parameter

please help!
what did I do wrong? I must have misunderstood the syntax described in Xp
help center.
