Windows 2000 stops responding to SMB requests and to RPC requests when you try to encrypt a file on a Windows 2000-based domain controller (895266)

SYMPTOMS

When you try to encrypt a file on a Microsoft Windows 2000-based domain controller, Windows 2000 stops responding to server message block (SMB) requests from the client computer. Additionally, Windows 2000 stops responding to remote procedure call (RPC) requests from the client computer.

This symptom occurs if the following conditions are true:

You try to encrypt the file by using local computer policy or domain policy.
The Windows 2000-based domain controller has Encrypting File System (EFS) disabled.

Additionally, an error message that is similar to the following is logged in the System log:Event Type: Error
Event Source: Active Directory
Event Category: None
Event ID: 1188
User: N/A
Computer: <servername>
Description: A thread in the directory is waiting in a remote procedure call (RPC) to directory <directory> performing a(n) <operation name> operation. The directory has attempted to cancel the call and recover thread id <thread id>. If this condition persists, stop and restart that Windows Domain Controller. Note When this problem occurs, you can still successfully ping the client computer from the Windows 2000-based domain controller.
