if you want to reset the identity coulmn in any table use The following line resets the Identity value for the table to 0 so that the next record added starts at 1
DBCC CHECKIDENT(‘Table Name’, RESEED, 0)
So i make Curssor to Select all tables with Identity column in any database then make reset to this tables

DECLARE @Table_Name AS NVARCHAR(100)
DECLARE @NewLineChar AS CHAR(2)
SET @NewLineChar = CHAR(13) + CHAR(10)
DECLARE Reset_Identity CURSOR
for
select o.name
from syscolumns c, sysobjects o
where c.status = 128  and c.xtype = 56 and c.colid =1 and c.offset = 2
and o.id = c.id
order by o.name
OPEN Reset_Identity

FETCH NEXT FROM Reset_Identity INTO @Table_Name
WHILE (@@fetch_status <> -1)
BEGIN
IF (@@fetch_status <> -2)
BEGIN
DECLARE @message varchar(100)
SELECT @message =  ‘DBCC CHECKIDENT(”’ + @Table_Name + ”’, RESEED, 0) ‘  + @NewLineChar +’GO’
PRINT @message
END
FETCH NEXT FROM Reset_Identity INTO @Table_Name
END

CLOSE Reset_Identity
DEALLOCATE Reset_Identity
GO

After you run this code on any database take the result becouse this code will genrate the reset identity column code in the database so if you take the result an run it in any database in this case you make reset  to the identity column
