Dears,
I am trying to join the ISE with our AD with no success, below the error logged in the ISE:
Error Description: Failed to find domain controller, please check network connectivity
Support Details...
Error Name: LW_ERROR_FAILED_FIND_DC
Error Code: 40049
Detailed Log:
Error Description :
Failed to find domain controller in domain 10.10.10.10 : domain does not exists in DNS
Error Resolution :
Please make sure that your DNS contains records for domain : 10.10.10.10, For further information please refer to the AD DNS diagnostic tools
Join steps :
13:51:40 Joining to domain 10.10.10.10 using user ise
13:51:40 Searching for DC in domain 10.10.10.10
13:51:40 Failed to find domain controller in domain 10.10.10.10 : domain does not exists in DNS
Although we are having valid records for both AD and ISE in the DNS, i am able to resolve the DNS of our AD when making NSlookup in the ISE.
I am not sure what is the issue?
Looking forward to hearing from you.
Regards,
Muhannad
