Exchange 5.5 Archving Agent

Stuck with Exchange 5.5 on this site for time being. Need to archive desperately from all mailboxes and Exchange Archiving Agent looks like it could be a useful solution here. However according to prereqs need ‘The EAA hotfixes in files “build81.zip” and “build82.zip” available from TechNet’ but of course the article hasn’t been updated since 2001 and I can’t get hold of them. Has anyone got them tucked away anywhere? Also any tips on use appreciated as the only article relating to it is install instructions…
Thanks.
