The maximum number of Active Directory Domain Services database sessions was reached, causing a request to the service to fail.  This is generally a symptom of high load on the server.  It can result in sporadic errors in applications that use Active Directory Domain Services.



User Action

(1) Check that an excessive activity load is not being performed.

(2) If necessary, increase the number of allocated sessions per thread by increasing the 'Maximum Allocated EDB Sessions per Thread' registry parameter.  This will result in Active Directory Domain Services using more memory.
