Are you using the DNS lookup option or directly entering a domain controller's FQDN?

Try the latter.

thanks ,

i used the FQDN and in the DNS i added the clearpass entry 

i'm sure that DNS can resovle the clear pass IP address and the AD address by using (network lookup ) from CLI

how can i 

Try the latter??????

thanks

thanks for your help 

after more time of searching on internet i found out the sol. of the problem and then i advice any one want to join clear pass to domain

1- make sure of NTP with the domain host (time sync.)

2- find out the FQDN (server hostname.domain name.root name)

ex (hpserv.hp.com) 

3-cheak your admin account privliges (can add machine to domain)

4- DNS of clearpass is the ip of the server domain
