[ Edited ]

HI Aruba,

 

First time to see this error aleart. See attached alert error " NO LOGON SERVER". does this mean the AD server is not reachable?

 

Thanks.

Re: Alert : NO Logon Server

That means that ClearPass cannot talk to any AD servers in the domain....  

How often does this happen?

Did you change the DNS server of clearpass to a non-AD server, perhaps?

Hi cJoseph,

 

Thanks for your reply.

 

We didn't change any settings in the clearpass and few domain user encounter this reject status.

 

Our appliance is using ClearPass version: 6.2.1.55992. we see this few times when we checked that this user/machine  is being rejected . but after 3 to 5 min we notice that it will be accepted again.

 

I can't find any services being restarted in the Event viewer similar with the  windbind error (Radius service service is restarted).

 

 

Thanks
