About this tag
The FSMO (Flexible Single Master Operations) roles are critical to Active Directory health, and WindowsForum.com discussions frequently cover role transfer, seizure, and troubleshooting. Common issues include FSMO roles pointing to decommissioned domain controllers, causing replication failures and service outages. Users share commands like netdom query fsmo and Move-ADDirectoryServerOperationMasterRole to diagnose and resolve conflicts. Topics also address backup strategies for AD-aware recovery, as FSMO role loss can disrupt identity services. Practical advice focuses on verifying role holders, cleaning up metadata, and ensuring DNS consistency to prevent FSMO-related errors.

    One DC is pulling FSMO from an AD server that doesn't exist, other DC sees FSMO fine

    I have 2 DC, one onpremDC, one hostedDC. There was some previous work where an RDS server was made a DC and FSMO moved to it, then the hostedDC was made the DC & FSMO moved to it, then AD removed from the RDS server.
