Hi

I assume you mean you got this error message?
"Failed to contact Kerberos service - error code 68 suggests that KDC is valid but domain DNS name is wrong"

This means that the "Domain DNS Name" you have specified isn't the correct one for this KDC Host (domain controller).

An easy way to find the correct DNS name for the domain is using nmap's smb-os-discovery script, e.g.:

nmap -sC -p445 --script=smb-os-discovery -n -Pn [kdc_host_here]

The "Domain name" field in the script output should contain the value you need.

If that doesn't work let me know...

Works! Thank you!
