I've had this with a more complex script but here is a cut down
version.

When I call session_start() in my script then link to another page that
calls session_start() I eventually get HTTP 500 internal server error.
This usually happens after 3 or 4 links. Its fine for the first few
links usually.

I'm running on the version of IIS that comes with XP Pro. 
I changed none of the php.ini setting during installation apart from the
session var directory which is now f:\data\websites\sessions.

The version of PHP is the binary of v4.1.2 for windows downloaded from
php.net. I'm running as CGI.

Here is an example of the code that exhibits the problem. If I keep
clicking the "Click me" link it throws the error after 3-4 clicks most
of the time.

<?
session_start();
?>

<html><body>
<a href="<?=$_ENV['SCRIPT_NAME']?>">Click me</a>
</body></html>

Ok this is wierd but I've noticed that once I started getting the HTTP
500 errors I couldnt get even a simple script eg <? echo "Test"; ?> to
work.

I tried checking the "Check that file exists" on the application
extension mapping in IIS and it all seems to work now. Odd.
