When attempting to access certain functions (e.g. "set program access and defaults") the computer (Dell Inspiron 710) returns a message stating that "This operation has been canceled due to restrictions in effect on this computer. Please contact your system administrator." Though no SysAd profile was created for this computer, I booted up in the Safe Mode and accessed the computer as the SysAd. It still does not allow access to the same functions. Is this a virus? Any thoughts on how to get around this?
