SYMPTOMS
When you work with a network share on a Windows XP-based computer, you may receive the following error message:

STOP: 0x000000C2

BAD_POOL_CALLER



CAUSE
When a Kerberos ticket times out, the Redirector (RDR) component has to update the ticket. To do this, the RDR starts a new session. Then, RDR returns the STATUS_RETRY status code to the top level handler that retries the previous operation.

In a CLOSE operation, the retry logic cannot roll back all the work that the logic has already done. Therefore, when the operation is retried, the client computer stops responding. The server does not stop a session on a CLOSE operation. However, when multiple operations coexist, the RDR may fail. Also, certain timing conditions, the CLOSE operation may expire.
