Thank You for very useful information.

I tried Your workaround and it works perfectly for me:
	test@server ~
	$ LOGONSERVER=server passwd
	Old password:
	New password:
	Re-enter new password:
	Password changed.

	test@server ~
	$

(Old value in $LOGONSERVER was \\server)

My server is standalone Windows Server 2008R2 Enterprise, so Microsoft's 
error message is not quite correct.

(On Yours 2008R2 problem didn't occur - interesting.)

Thank You.
