When a remote network resource is connected to by using a UNC name, the user's credentials must be validated. A UNC connection works through Multiple UNC Provider (MUP) by using Server Messaging Blocks (SMBs). An SMB called SESSION SETUP and X is used for the connection, and at that time the user's credentials are passed to the network resource.

If the resource is a domain controller that maintains the user account, then the validation will occur locally on that computer. However, if the resource must use pass-through authentication to validate the user, the secure channel mechanism listed earlier in this article is used. The network resource will request a validation of the user from its domain controller, and if the user's credentials are not valid, the domain controller will return an error to the network resource.

Also, the domain controller will increment its usri3_bad_pw_count for that user.

This will all take place transparently to the client workstation that originated the request.

The network resource will return a message to the client workstation.

That message will have the NT status code 0xC000006D, STATUS_LOGON_FAILURE
