SELECT distinct
Max(CONVERT(VARCHAR,A.ActiveDate,101)) sortdate,
CONVERT(VARCHAR,datename(month,A.ActiveDate)) + ' ' + CONVERT(VARCHAR,YEAR(A.ActiveDate)) ActiveDate
FROM
Articles A,
ArticleGroupLink GL
WHERE
A.ArticleID = GL.ArticleID and
GL.GroupID = 44
GROUP BY ActiveDate
order by
sortdate desc, --CONVERT(VARCHAR,A.ActiveDate,101) desc ,
CONVERT(VARCHAR,datename(month,A.ActiveDate)) + ' ' + CONVERT(VARCHAR,YEAR(A.ActiveDate)) desc

I need to get distinct ActiveDate column. Tried to get the max of the sortdate and group by ActiveDate that is not working for me. How can I get this done?

looks like you need this

SELECT ActiveDate,MAX(sortdate) AS sortdate
FROM
(
SELECT 
CONVERT(VARCHAR,A.ActiveDate,101) sortdate, 
CONVERT(VARCHAR,datename(month,A.ActiveDate)) + ' ' + CONVERT(VARCHAR,YEAR(A.ActiveDate)) ActiveDate
FROM 
Articles A,
ArticleGroupLink GL
WHERE
A.ArticleID = GL.ArticleID and
GL.GroupID = 44
)t
GROUP BY ActiveDate
order by 
sortdate desc

Always better to specify the length of VARCHAR during convertion
