DFSUtil in Windows Server 2003 VS DFSUtil in Windows Server 2008

1. New Command Line Interface (CLI)

DFSUtil.exe in Windows Server 2008 comes with a new CLI, which is based on Keywords, Required Parameters and Optional parameters instead of Switches and Arguments. With this change, we intend to make the usage of the commands clearer and easier.

Navigation through Keywords is more friendly, giving the information needed to execute a task.

An example of this:

To create the new Domain-Based Namespace Projects which is going to have a Root Target at the Server NewYork, with the old CLI the user had to type

DFSUtil.exe /AddFtRoot /Server:\\NewYork /Share:Projects /Comment:”Projects in New York”

With the new CLI

DFSUtil.exe Root AddDom \\NewYork\Projects “Projects in New York”

The new CLI not only gives the necessary information for the task to be executed, but display hints to help resolve tasks related as in when you are creating a namespace you would like to add root targets to it.

  • Ask the Directory Services Team : Five Common Causes of “Waiting for the DFS Replication service to retrieve

  • Can you tell me if there is a CLI for building DFS replication?

  • It looks like when using the "DFSUtil link add" command, it puts everything in lowercase when it creates the link.  For example:

    dfsutil link add "\\Mydomain.pri\Links\Test\This is A Test" "\\fileserver1\share\This is A Test"

    The DFS link it creates is "this is a test" instead of "This is A Test".

    This is quite anoying, and frankly I don't understand why it would even do this.  Is there a work around for this?

  • Hi, Nelson,

    Thanks for reporting this issue. This is a know issue in dfsutil.

    As a work around please use dfscmd /map to create links in dfs namespace.

    Thanks

  • Hi

    I have a problem with my DFS setup running Windows Server 2008. It's Active Directory integrated.

    If a client doesn't have our fqdn as as dns search suffix the client cannot resolve the dfs. I guess this is due to the server replying with the netbios name instead of the dns name. I've set the DFSDNSConfig to 1 on both my dfs servers, but I am unsure if I need to delete the whole namespace and create it again as this article describes for Win2003. http://support.microsoft.com/kb/244380

    Can any of you guys point me in the right direction?

    Thanks

    Sebastian
