You've been here long enough to know that you need to post DDL, consumable data and desired results to get a working solution.

Try
select name
from admins
where group in ('TJA','tJB','tJK','tnr')
group by name
having count( distinct group)=4

100% in agreement with that, but I'm feeling generous this morning.
WITH admins ([group], name) AS
(
SELECT 'TJB','ICH'
UNION ALL SELECT 'TJK','ICH'
UNION ALL SELECT 'TJA','ICH'
--UNION ALL SELECT 'TNR','Unify'
)
SELECT name=MIN(name)
FROM admins
WHERE [group] in ('TJA','tJB','tJK','TNR')
HAVING COUNT(DISTINCT name)=1;
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
