SYMPTOMS
Microsoft Windows may stop unexpectedly and an error message may appear on a blue screen if the following conditions exist:  The Directory Services Client for Windows 95 and Windows 98 is installed (this is available on the Microsoft Windows 2000 Server CD). You map a drive to a Distributed File System (DFS) fault-tolerant (domain) DFS root, using the following format:

\\ \

 You try to access the mapped drive.

If you right-click Network Neighborhood and then map the drive (this automatically opens a shell folder), you receive the following error message:

Windows

An exception 0E has occurred at 0028:????????.

The current application will be terminated.


 * Press and key to attempt to continue.


 * Press CTRL+ALT+DEL to restart your computer. You will

lose any unsaved information in all applications.

Press any key to continue

If you map the drive in a logon script (or from a command prompt) and then double-click My Computer, or if you click Start, click Run, and then type a path on the drive (for example, :), you receive the following error message:

Windows

An exception 0E has occurred at 0028:???????? in VXD IFSMGR(04)

+ 0000B006. The current application will be terminated.


 * Press and key to attempt to continue.


 * Press CTRL+ALT+DEL to restart your computer. You will

lose any unsaved information in all applications.

Press any key to continue

If you try to access the mapped drive from a command prompt or from a logon script, you receive the following error message:

Title: MS-DOS Prompt (or icon title)

Text: This program has an illegal operation and will be terminated.

Quit all programs, then restart your computer.

If the program consistently encounters problems, click the Start button,

then select Help, Troubleshooting, and 'If you have trouble running

MS-DOS programs'.

[ OK ] [ Details >> ]

The program encountered an invalid page exception.

Fault location: 0028:0009

Interrupts in service: None

[ Ok ]



CAUSE
The client redirector (Vredir.vxd) and DFS device (Dfs.vxd) do not interact correctly for a domain name DFS root mapping, causing the installable file system manager (Ifsmgr.vxd) to fill in a set of file system function handlers for the associated shell object that are not valid.



RESOLUTION
To work around this problem, use a DNS-style fully qualified domain name (FQDN) that is similar to the following example:

\\ \

This method works correctly only if the FQDN is NetBIOS compatible (that is, the domain name contains fewer than 16 characters).

This method may not work if the fault-tolerant root is hosted on a domain controller. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
