Hi,
Jopi213 I see that our error is not a like at this point. I did have Microsoft Identity Integration Server as well I had the "C:\Program Files\Windows Azure Active Directory Sync"
I have been able to move a bit further (now another issue..)
1. I uninstalled DirSync
2. Installed AD DS on the DirSync server and promoted it to domain control.
3. Hence I reinstalled DirSync.
Now I am running into some new issues with "Enable-MSOnlinePasswordSync access denied", which I think is caused by network configurations.
Feel free to ask for further information.
