We got 3 domain controllers (2008 and 2008R2) where one hold all fsmo roles exept the Infrastructure Master.
If we create a new account in Active Directory we get the error "The direcotry service has exhausted the pool of relative identifiers". We get this error on all domain controllers
i ran dc diag and discoverd that the RID Manager role failed whit " The DS has corrupt data: rIDAvailablePool value is not valid"
i tried to seize the role, but it didn't need seizing.
i removed some old entries of long long long retired domain controllers
tried to setup new domain whit trust but again identifiers error on making a trust
any suggestions are welcome.
