Reset Identity for the table in sqlserver

CREATE TABLE IdentTest (Ident INT NOT NULL IDENTITY (1,1), varfield varchar(100))
INSERT INTO IdentTest VALUES ('abc')

DBCC CHECKIDENT ('IdentTest',RESEED,100)

-- here 100 starts identity from 101 if is there any data in table otherwise it starts from 100, for 1 you have to  use 0
INSERT INTO IdentTest VALUES ('def')

SELECT * FROM IdentTest
--Note: if the inserting with already existing identity, then it will raise the error.
