Rearrange Identity Column values after delete in SQL Server

Table Name - Student

SNO        Name            Address

1           Shatrughan     Bilaspur

2           Anup              Mumbai

3           Shankar          Delhi

and After Perform this query :- Delete from Student Where SNO=2 ;

Table look like this  

SNO        Name            Address

1           Shatrughan     Bilaspur

3           Shankar          Delhi

But I want to rearrange the table like

SNO        Name            Address

1           Shatrughan     Bilaspur

2           Shankar          Delhi

Thanks for reading.....
