Additional Data

Error value:

8446 The replication operation failed to allocate memory.



In Windows 2003 the default Kerberos token is a fixed size of 12,000 bytes.  Transports such as remote procedure call (RPC) and HTTP use the fixed token size when they allocate buffers for authentication. When communicating with domain controllers via a trust RPC is used, and authentication information is exchanged.  If the authentication information to be exchanged via Kerberos is larger than the default size then the application(s) may fail with various errors as show above.


The replication errors shown above are usually between domain controllers from different domains.



Use the article below to set the Kerberos token size to its maximum of 65,535 bytes.
