SYMPTOMS
You can open the Distributed File System MMC snap-in on a Windows Server 2003-based computer by using one of the following methods:
 * You click Start, point to Administrative Tools, and then click Distributed File System.
 * You click Start, click Run, and then type dfsmgmt.msc in the Open box.

In the following scenario, the changes that you make are not retained:
 * You click Distributed File System in Administrative Tools.
 * You add a new item, such as a new root.
 * You close the Distributed File System MMC snap-in, and then you reopen the snap-in.

However, in the following scenario, the changes that you make are retained:
 * You type MMC in the Open box, and you then open the Distributed File System MMC snap-in.
 * You add a new item, such as a new root.
 * You close the Distributed File System MMC snap-in, and then you reopen the snap-in.



CAUSE
This behavior occurs because the MMC snap-in is set to Console mode when you type MMC in the Open box. In Console mode, any changes that you make are retained

However, MMC snap-ins that reside under Administrative Tools are set to User mode. User mode prevents you from adding items and from saving any changes. Additionally, the Distributed File System MMC snap-in is set to User mode when you type dfsmgmt.msc in the Open box.



WORKAROUND
To work around this behavior, you can create a custom MMC snap-in. To do this, follow these steps:
 * 1) Click Start, click Run, type mmc, and then click OK.

Note The empty console has no management functionality until you add a snap-in.
 * 1) On the Console menu, click File, and then click Add/Remove Snap-in.

Note The Snap-ins added to box only lists Console Root.
 * 1) Click Add.
 * 2) In the list of available stand-alone snap-ins, click Distributed File System, click Add, and then click Close.
 * 3) Click OK to close the Add/Remove Snap-in dialog box.

Note It is important to plan the structure of your custom snap-in tool so that it is functional and it is easy to use.
