Think I have found the problem. Xrdp was installed and KRDP didn't like that, must be jealous. Anyway removing Xrdp and packages with reboot seems to have solved it.
Problem 2, now that I have my machines talking to each other on Krdp, how do you ensure the sharing setting remain after reboot. It is ok if I dont reboot can connect without trouble but if I reboot the remote machine it asks again for sharing permission on the remote despite the box for allow automatically for future sessions being checked.
