Cisco Identity Services Engine (ISE)

[Rickey369]

Hi All,

After deploying ISE , I'm encountering some problem with the few desktop users as the authentication is very slow (1-3 hours) when they connect LAN cable to their desktop. 

Is this the probelm with ISE? How can i troubleshoot this? Sometimes i need to continuous restart the desktop to get authenticated to LAN network. ( Ie; to get the proper domain network, I usually get "network 3" or "network 1" instead of getting abc.com (<-- Just an example)

This problem is only with few desktop users. Most of the desktop works fine.

Is this the problem with domain controller ?

or dot1x Authentication issue  ( But ISE shows Authentication success)?

Please Help!!

Have you tried to connect the user in question directly on a switchport with no 802.1X authentication enabled and with the quarantined VLAN assigned to the port and see if you get the same result?

I have not tried that. let me try this troubleshooting.
But when i connect some other laptop to that port where the user finds issue, it works !! and when i connect it back to old laptop ( laptop of the user having issue ) it shows network 2 or network 3 .

I have also tried with no 802.1x , it still shows network 2 or network 3 , but the user is able to access internet and other applications.
