MISCM stops with an error message: 'Error in [50] CreateNewDomain FAILED' is quite a generic error pointing to various issues such as:
- Data in the DCT file.
- Version of the DCT file being used.
Majorly in Exchange this issue relates to permissions.
1. Ensure that the add required permissions as described on
https://support.avaya.com/css/P8/documents/100059605 (Page 35 to 39)
2. Create the Octel container at root level, with full control permissions for Account Operators Group.
3. Run MM Permissions Checker tool and check all the items are green.
Even if the issue is not resolved after permissions check, please raise a ticket with the Avaya MM Backbone team.
