ERROR_DS_NO_RIDS_ALLOCATED - 8208 (0x2010)
The directory service was unable to allocate a relative identifier.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_DS_NO_RIDS_ALLOCATED error code indicates that the directory service encountered an issue while attempting to allocate a relative identifier (RID). RIDs are unique identifiers assigned to security principals within a domain, such as users and groups.
Error Details
This error typically occurs during operations involving user or group creation, where the system attempts to assign new RIDs. If no available RIDs can be allocated, this error is returned. The RID pool must contain sufficient free entries for successful operation; otherwise, the allocation fails.
Usage Context
The ERROR_DS_NO_RIDS_ALLOCATED error is relevant in scenarios involving domain user or group management, particularly when creating new security principals. It may also appear during operations that require dynamic assignment of RIDs, such as certain Active Directory operations.
Developer Interpretation
Developers should interpret this error as an indication that the system has exhausted its available RID pool. This can be due to a variety of reasons, including high user or group creation rates, insufficient initial allocation of RIDs during domain setup, or issues with the RID master role holder in the domain.
Related Errors
ERROR_DS_RID_EXHAUSTED(8209): Indicates that all available RIDs have been used up and no new ones can be allocated.ERROR_DS_RID_MISMATCH(1356): Occurs when a RID is not consistent with the expected value for a given security principal.
FAQ
Q: What does the ERROR_DS_NO_RIDS_ALLOCATED error mean?
A: It indicates that no available RIDs can be allocated, typically due to an exhausted pool of RIDs.
Q: How can I resolve this issue?
A: Ensure sufficient RIDs are available by checking domain setup and RID allocation policies. Consider increasing the initial allocation or adjusting user creation rates.
Summary
The ERROR_DS_NO_RIDS_ALLOCATED error signifies that the directory service cannot allocate a relative identifier, which is critical for managing security principals in Active Directory domains. Developers should focus on ensuring adequate RIDs are available and properly manage domain setup to prevent this issue.
