Windows Server 2003 security patches checked versions

Hi All,

We want to test using the full checked version of Windows Server 2003.
However, the security patches will not install on this version so we get hit
with SARS. Do checked versions of the patches exists? If not, will setting
up a partially checked build after installing a free fully secured version
prevent SARS infection? We would prefer a fully secured checked build but
that may not exist.

Best Regards,
Joe
