How can we find the Time Zone of the remote machine if the remote machine is in the same network and is easily accessible.I know PsExec can be used but i want it without user name and password.

You're going to have to have the username/password to access anything on a remote computer, think of the security risk if you didn't need it.

Second, what research have you done, or code attempts have you made to solve this?
