1029. Fine.
However, I have noticed that after a reboot inetinfo is listening on 1029
but after a restart of the inetinfo related services, inetinfo is listening
on a port different from 1029, e.g. 1076!?
Hmm... Where can I find documentation on this behaviour?

I can't point you to a URL, but you'll find a lot of systems that work this
way. Ports > 1024 (high order ports) are dynamically allocated, so if you
have a service or app that needs remote administration it will use a port >
1024. This port may vary from reboot to reboot depending on what other
services also need ports - as the services start up, they request a high
order port from the OS, and bind to it.
On Windows, the RPC Port Mapper service on port 135 tells your remote admin
tool which high-order port to connect to. So, if you open IIS Manager on a
remote machine, and decide to admin your server. It will connect to port 135
on the server to find out what port IISAdmin is listening on, and then
connect to that port.
