Issue

The Server Message Block 2.0 (SMB 2.0) file sharing protocol is disabled on this file server.

Impact

Client computers cannot communicate with the server by using the SMB 2.0 protocol. As a result, file transfers might be slower, the file server might not be able to service as many connections, and new functionality such as support for symbolic links or durable handles will not be available.

Resolution

Use Registry Editor to enable the SMB 2.0 protocol.
