I have two forests:
abc.com forest with a child domain xyz.abc.com and a second forest called abc.net.
abc.com and abc.net have the same NetBIOS name "abc"
abc.com domain it's an empty root domain, all resources and accounts are created in xyz child domain
I have to create a trust between xyz.abc.com and abc.net but it's not possible because xyz has already a TDO (trust domain object) with abc name?
the constraint is caused only between roots domains.
What's the risk to rename the NETBIOS the root domain of abc.com? in this forest we have Exchange 2010
What is the impact if we broke temporarly the trust between child and parent root ?
is there a work around to permit mutual acces the resources between xyz.abc.com and abc.net without double authentication
Thanks
