Hi, all! Sorry for my English! There are peer-to-peer network, 20 computers with WXP, 2 servers W2k3Ent, each computer use Nod 32 2.70.39. Updates are loaded by one of computers with WXP, there "the mirror" is created, all other computers are updated from the "mirror". When Nod 32 used on W2k3Ent attempts to get updates from the mirror, I receive an error message: "Error during attempt of reception of the certificate of the user. No user is registered". Thenks!
