SQL-Server

I Have a Table Like This:

____________________________________________________________________
******ID******post_title_code******post_eff_date******site****empno
____________________________________________________________________
******01********1011************01/10/1999*******1070*****123
******02********1011************01/10/2000*******1070*****123
******03********1011************01/10/2001*******1070*****123
******04********1012************01/10/2002*******1070*****123
******05********1000************01/10/2003*******1070*****123
******06********1000************01/10/2000*******1070*****123

Now i have different ID's but the post_title_codes are same in various places..Now i want the resultant to display the record but the post_title_code should be distinct and in that it should display the record with highest ID..
E.G the output of the above mentioned Table should be like"
____________________________________________________________________
******ID******post_title_code******post_eff_date******site****empno
____________________________________________________________________
******03********1011************01/10/2001*******1070*****123
******04********1012************01/10/2002*******1070*****123
******06********1000************01/10/2000*******1070*****123

Here in this output we can see that the post_title_codes are distinct and the from them only that record is displayed which had the MAXIMUM ID..
like in post_title_code for '1011' had three records so it displayed the one with the highest ID among these three records..

Any help would be highly appreciated..
Thank You..
