Hello, I have got the following SQL Query which gives me the list of birthdays in a month.
it is coming up with some Duplicates, how can I get rid of those, and it also comes up with a record called Admin User which I would like to eliminate as well.
  select   e.given_name +' '+e.surname as full_name
  from dbo.q2employees e 
  where MONTH(e.[date_of_birth]) = MONTH(GETDATE())

You can use the DISTINCT key word to eliminate duplicates from a result set.

Then you add an extra AND to refine out Admin User.  Assuming that Admin is the first name and User the last name you'd do:
select   DISTINCT e.given_name +' '+e.surname as full_name
from dbo.q2employees e 
where MONTH(e.[date_of_birth]) = MONTH(GETDATE())
and not (e.given_name = 'Admin' and e.surname = 'User')

are you sure they are duplicates? may be different employees with same name.
try

select   distinct e.given_name +' '+e.surname as full_name, e.[date_of_birth]
  from dbo.q2employees e
  where MONTH(e.[date_of_birth]) = MONTH(GETDATE())
