Hi,
thanks for the help.
At the end the registry entry works and did work before. However, I did not know that there is a known issue regarding ini files. Here an answer I recieved from Solarwinds Support:
...yes it is a known issue that the registry changes
works but they are not carried over when doing a settings transfer using the
INI file. The reason behind this is because this is not recommended as mentioned in the admin guide...
So I guess I have to life with it :-)
