Add WITH TIES to your select top 20. Hope the following helps illustrate what you need:

create table dbo.production(

ServerName varchar(20),

ServerState varchar(10)

);

insert into dbo.production

values ('ABC','A'),('ABC','B'),('ABC','C'),('ABC','D'),('ABC','E'),

('CDE','A'),('CDE','B'),('CDE','C'),('CDE','D'),('CDE','E'),

('FGH','A'),('FGH','B'),('FGH','C'),('FGH','D'),

('ZXC','A'),('ZXC','B'),('ZXC','C'),('ZXC','D'),('ZXC','E')

Select top 1 with ties COUNT(ServerState) StateCount ,ServerName

FROM production

Group By ServerName

Order By COUNT(ServerState ) Desc;

drop table dbo.production;

Please note that I was running this in a sandbox database and clean up after using the table.
