Sharing tab missing in Properfies for files in network share

I am doing this on Windows Server 2008 R2.  The Sharing tab is missing in file Properties in Windows Explorer for files located in network shares, including administrative shares.

This article says it's a problem: http://support.microsoft.com/kb/177659 but it's quite old and the suggested actions do not solve my problem.

How can I set sharing permissions without RDP into a remote machine?  ICACLS does not seem to be able to do it.

Thanks.
