I created a user and joined user to Administrators, but
they cannot install programs like MS Office. Why do they
have to log on as Administrator. No changed were made to
local policies and no domain policy is being enforced.
Thanks.

They should not have to logon/logoff if their account is in the local
administrators group. I would run the following command and verify that
the account they are using is truely in the admin group.
net localgroup administrators
Make sure they are using the correct account. Do you see unresolved SIDS
in this group?
