Disabled "Change" and "Advanced" buttons in "File Types" tab

[SSGP]

Hello,

I find that on my Windows 2000 Adv. Server machine
the "Change" and "Advanced" buttons under Details section
of the "File Types" tab of the Control Panel-Folder
Options are disabled for all file types listed.
Also, The "New" and "Delete" buttons too are grayed out.

Can some one tell me where and what settings I would need
to change so that the "Change", "Advanced" as well
as "New" and "Delete" buttons will become active?

Thanks,
SSGP

Found the reason and the solution in KB article Q257592

The relevant info from the article -
On computers running Windows 2000 Terminal Services in
Application Server mode, the UI may be locked down so that
no one can change file type associations (not even
administrators). This is done so that you can only edit
the entries programmatically or by using MSI-based
applications. This ensures that an inadvertent change in
the UI does not effect the global file type associations
across the computer running Terminal Services and all of
its users. When this policy is enabled, the New, Delete,
Change, and Advanced buttons are unavailable on the File
Types tab of the Folder Options tool in Control Panel.

You can enable this functionality by changing the
following registry entry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersi
on\Policies\Explorer] "NoFileAssociate"=dword:00000000
