Event InformationAccording to Microsoft:
CAUSE:

This problem occurs because Windows Server 2003 does not support creating DFS links from folders that are under a volume mount.
WORKAROUND :
To work around this problem, use one of the following methods:
• Attach two disks together by using spanned volumes instead of using volume mount points.
• If you are running Windows Server 2003 Enterprise Edition, you can use multiple DFS roots to link to each other. For example, if you have a volume D and a volume E, you can mount each as a DFS root. Then, you can create DFS links from folders on volume D that point to folders on volume E.
Steps to reproduce the problem :
Note:
You must have two computers to follow these steps.
1. On a Windows Server 2003-based computer, create a folder structure that is similar to the following:C:\Data\F1
2. Open Disk Manager, and then mount a hard disk in the C:\Data folder.
3. In the DFS snap-in, create a stand-alone DFS root. Set the root folder as C:\Data and use the following parameters:
Server Name = Your_Server_Name
Root Name = Data Folder to Share = C:\Data
4. Try to create a DFS link from the DFS root that you created. Use the following parameters:
Link Name = F1
Path of target = \\Your_Second_Computer_Name\Data2
Expected result: The DFS link is created.
Actual result: You will receive the error message that is mentioned in the Symptoms section.
Reference LinksYou cannot create DFS links that point to a folder that is under a volume mount point in Microsoft Windows Server 2003
