I am having an issue on my laptop which is running Windows XP Pro.
Other domain users are unable to log on to my machine. When they try I
get an error stating that Only Administrators can log on to computer
using UserName and Password. I also notice that on the Ctrl-Alt-Delete
login dialog it says "Enter the credentials of administrator". I have
tried adding the Guest and Everyone user groups to the Log On Locally
local security policy, but that didn't make any difference. Other
machines on the domain do not have the same limitation. Any ideas?
