Possible to Circumvent ZAK Using Explorer.exe as Embedded Object (182367)
The information in this article applies to:
- Microsoft Zero Administration Kit for Windows NT Workstation 4.0
This article was previously published under Q182367 SYMPTOMS
After you install Windows NT using the Zero Administration Kit (ZAK) with a
desktop setup that does not permit users to launch Windows NT Explorer, you
can still gain access to Windows NT Explorer when in a Microsoft Office
application. This is achieved by inserting an object into the document and
typing in the path and file name from the import box.
CAUSE
The Explorer.exe file has Read & Execute (RX) special permissions, which
enable the folder to be opened from within the application. The file is
first read before it can be run. These permissions are set during the ZAK
install when Acls.cmd is run.
RESOLUTION
To resolve this issue, remove the Read (R) special permission from the
Everyone Group. If the file cannot be read, it cannot be run. However, you
must retain the Execute (X) special permission so that Explorer remains as
the active desktop. Use one of the following methods.
Method One- Start Explorer and locate Explorer.exe in the %SystemRoot% folder.
- Right-click the executable file and select Properties.
- Select the Security tab from the Properties window and click the
Permissions button.
- Double-click the Everyone Group and view the Special Access dialog box.
- Remove (clear) the Read(R) attribute and confirm the changes.
Method Two
Edit Acls.cmd and change the following line from:
cacls.exe explorer.exe /t /e /g everyone:r
to:
xcacls.exe explorer.exe /t /e /p everyone:x
where:
xcacls is used because special permissions are being set
/p is used to replace existing permission
x is used to grant execute permission
NOTE: xcacls is a resource kit utility and should be accessible through the
path or referenced explicitly.
