Hi Steve,
did you check how your IP filters are setup on external network card on
Win2K3 server? Do you have correctly marked external and internal network
cards (IP filters are different for external or internal card!)
Are clients trusting the certificates that you issued? If you think the
problem is in certificates, use MS CHAP v2 for test, till it works with MS
CHAP v2 then switch to certificates.
