Select And UPDATE Statement Help! (Using SQL Server)

I have a table which I need to obtain data from but am having a problem with select statement.

 Specifically, I have a table that has multiple records for a particular hostName where the name of the host is either a shortname (say "Larry") or a long name (say "Larry's"). 

       I need to display only the long names (NOT THE SHORT NAME records with the similar hostName).

      Select winsHostName, len(winsHostName) from winsData where winsClientIPAddress IN
                     (SELECT winsClientIPAddress
                      from winsData
                     Group By winsClientIPAddress
                     Having count(winsClientIpAddress) > 1)
                     Order by winsHostName

   Which returns data

                    Name               Length

                    ATVDDR          6
                   ATVDDR1         7


This is a s far as I can get but,

Now, I need to list all remaining table fields based on the Name with the longer length and this is where I run into trouble.

               The output should read per below with the remaining table fields which I cannot seem to extract with nested select statement

                            Name              IP Addr     Location

                            ATVDDR1       1.1.1.1     2ndFloor

I tried adding another GROUP BY by this gets me no where because I do not need to execute another aggregate in select statement. Maybe I need to use INNER JOIN 

 Please advise any assistance.
