When we shipped Windows Server 2003 R2, many customers requested a way to enable and disable referrals for a link target using command line. Neither dfscmd.exe nor dfsutil.exe back then provided a way to do this.

In response to those requests, Dan Lovinger published Modlink, command-line method to enable and disable referrals for a link target. Until today, we provided the source code for Modlink in the blog. But compiling the code can be a hassle, so in order to make it available for more people, we opened our first SSD open code project in Codeplex. Now you can download Modlink compiled!

Modlink Open Source project page: http://codeplex.com/modlink

Download Modlink binaries here: http://www.codeplex.com/modlink/Release/ProjectReleases.aspx

And source code here: http://www.codeplex.com/modlink/SourceControl/ListDownloadableCommits.aspx

Windows Server 2008 users, please note:

Due to many requests, feedback and user adoption we had for Modlink, the DFS Namespaces team decided to make Modlink functionality in-box for Windows Server 2008. So, if you are a Server 2008 administrator, you don’t need Modlink anymore.

To enable and disable referrals using DFSUtil in Windows Server 2008, from an elevated command prompt, use

dfsutil property state <DfsPath> [<\\server\share>]

------ STATE Commands Supported ------

Online                Set state of folder or folder target to Online.
Offline               Set state of folder or folder target to Offline.


> DFSUtil property state offline \\contoso.com\DomainNamespace\Link \\Server\Share

We hope that helps some people! And don’t forget to keep sending us your feedback.
