Tanjay (LG-Nortel) “Cannot download certificate because domain is not accessible. If the problem persists, contact your system administrator”

Posted by Mino on February 20, 2009

I had this problem with the Tanjay new phone when I plugged it to my DHCP network and i was not able to find the problem .

However after little trials i found the below solution.

 Normally there is two ways to logon to Active Directory:

1.       Domain\username

2.        username@domain.local

 

I was getting this certificate error because I was trying username@domain.local  however I have found that if you log into the phone using domain.local\username

 

The phone is able to find the domain and download the certificate.

 

I found this out while doing a packet trace on the phone one day and found this search behavior

 

Netbios AD name: test

UPN Suffix: test.local

DNS Suffix: abc.com – this is given to the phone via DHCP

 So the DNS queries from the phone was this

 

Away from all these complicated trace like stuff, if you want to solve this problem just login with domain.local\username   and it will work fine  J
