DISTINCT is misspelled.

Above table name seems misspelled.

Above join is incorrectly referencing the same column, it should be the
column from the other table.

Here is the query a bit cleaned:

SELECT DISTINCT U.Title,
W.Title,
G.Title
FROM WebGroups AS G
JOIN WebGroupMembers AS M
ON G.WebID = M.WebID
JOIN Webs AS W
ON G.WebID = W.WebID
JOIN UserInfo AS U
ON M.MemberID = U.MemberID
WHERE G.Title = 'Admin'
