I have migrated SQL 2008 R2 server from one domain to another, I have changed the service SSRS service account using SSRS config manager. SQL is working fine and I have problem with SSRS using login from different trusted domain. Before migration all users, service account and servers are in one domain (DomainA). I have migrated the servers and service accounts to new domain (DomainB) and user migrated to new domain (DomainC). DomainB and DomainC trusted each other (two way trust). I can access the reports page using the service account (ex: DomainB\svc1) and other account exists in DomainA (ex: DomainB\user1) BUT I can’t access the reports using accounts in DomainC (ex: DomainC\user1). I have granted the user (ex: DomainC\User1) system administrator access in Site Settings and added local administrator group no luck. Can you guys point me to the right direction where I can access the reports using accounts in DomainC (ex: Domain\user1). Thanks, Mohammed. Mohammedu
