https://community.cisco.com/t5/network-access-control/no-logon-servers-available-to-service-the-logon-request/m-p/2702796#M54816 <P>Currently have an issue with new user attempting to logon to workstations with anyconnect and NAM installed connected to a 802.1x switchport. If&nbsp;the user typed in the incorrect credentials they received the following errors "no logon servers available to service the logon request ", instead if windows&nbsp;telling the user that&nbsp;incorrect username or password was enter. On ISE side I see it&nbsp;logged as&nbsp;the user enter the wrong credentials.&nbsp;If a user typed in their credentials correctly, the no error. I been looking at the packet capture, when the user enter the wrong password I&nbsp;don't see traffic between the workstation and&nbsp;the AD servers, it just goes straight to the error. I have a permit all DACL&nbsp;applied during on the switchport during&nbsp;machine authentication process, so no traffic should be blocked.&nbsp;I have&nbsp;contacted TAC on this issue, they haven't see this issue before,&nbsp;so it suppose to work as design. I was wondering has&nbsp;encounter this issue, thanks&nbsp;</P> Mon, 11 Mar 2019 05:53:39 GMT philiplor 2019-03-11T05:53:39Z https://community.cisco.com/t5/network-access-control/no-logon-servers-available-to-service-the-logon-request/m-p/2702796#M54816 <P>Currently have an issue with new user attempting to logon to workstations with anyconnect and NAM installed connected to a 802.1x switchport.

Also, are you changing vlans at any point during authentication of machine or user?</P> Wed, 15 Jul 2015 17:10:00 GMT https://community.cisco.com/t5/network-access-control/no-logon-servers-available-to-service-the-logon-request/m-p/2702797#M54817 jan.nielsen 2015-07-15T17:10:00Z
