The AD Op Master Response Monitor failed consecutive attempts to bind or ping the relative ID (RID) operations master (also known as the RID flexible single master operations (FSMO) role holder). This is more than a transient error, and it should be investigated.
Note: A failure to contact the RID master may prevent the creation of new objects in the directory.
