Posted September 28, 201113 yr Hi, I am having an AD environment with 5 DCs. ns1.test ns2.test ns3.test ns4.test ns5.test FSMO role distribution was pending, so virtually ns1.test had all the roles and was the only DC which had writable partition. While some testing I lost ns1.test. I format ns1.test and tried again to attached to domain, but its giving an error saying "You cannot attach any new DC till the time RID master is down" I have all the other four DCs up and running, but I am not able to attach ns1 again to domain. Even though its an testing environment but it has some critical test result and requirement. I will highly obliged if someone can help me on this. - Prashant
