Converting Mysql 2 Sql 2000

how do i go about converting the Mysql Script below to Sql Server Script ????

CREATE TABLE cat (
id int NOT NULL auto_increment,
name char(20) NOT NULL default '',
PRIMARY KEY (id)
);

INSERT INTO cat VALUES (1,'Not Categorised');

ALTER TABLE cat AUTO_INCREMENT = 5;

i want a script that:
creates the table
inserts a row of data and then
sets the increment field to start at 5

i tried using identity(1,1) and
SET IDENTITY_INSERT cat ON;
INSERT INTO cat VALUES (1,'Not Categorised');

but when i enter the data in i get the error below

An explicit value for the identity column in table 'cat' can only be specified when a column list is used and IDENTITY_INSERT is ON.

please can anyone help or advice

thanks
