IE 5.5 global restriction of temp int files

[Guest_imported]

Hi,

we have some PCs with NT4.0 SP6 and IE 5.5 running. Some of them have 30+ users. Now it is easy to keep Temporary Internet Files size low for a specific user. I cannot find a method to restrict this globally, i.e. each user has a standard size that is based on the size of the harddrive.
That way a lot of junk accumulates very quickly. Any way I can prevent this? I have admin rights.

Thanks.
