Sysprep and Windows 2000 Pro

Archived from groups: microsoft.public.win2000.setup_deployment (More info?)

i've used the sysprep tool successfully in the past to prepare my system for
cloning. However, now when I run sysprep (v1.0 or v1.1) I get an alert that
I must be logged on as administrator to execute the program even though I am
actually logged on as adminstrator. My prior successful attempts at running
sysprep were a over a year ago -- since then the only significant change to
my system is is the SP4 update.

Has anyone encountered a similar problem? Any help would be much
appreciated.
