topic VPN 3000 Authentication from Windows 2000 PDC in Network Access Control https://community.cisco.com/t5/network-access-control/vpn-3000-authentication-from-windows-2000-pdc/m-p/4876#M6815 <P>We have a problem authenticating VPN 3005 users from Win 2000 Server. We can ping the server from the concentrator, but we can't authenticate (even if test) users. But we could authenticate from the radius server which is on the same LAN (both servers on the private side, so no filter problem on the private interface). In the documentation I could'nt find anything regarding authentication from Win 2000. Can the VPN 3000 series only authenticate from the Win NT 4.0 or does it support Win 2000 too? Does anyone have any experience in this issue?</P><P>Thanks</P> Fri, 21 Feb 2020 17:56:40 GMT uoktay 2020-02-21T17:56:40Z VPN 3000 Authentication from Windows 2000 PDC https://community.cisco.com/t5/network-access-control/vpn-3000-authentication-from-windows-2000-pdc/m-p/4876#M6815 <P>We have a problem authenticating VPN 3005 users from Win 2000 Server.
