NTLM Configuration error

Unfortunately there is not enough information provided in the overview screen of Wireshark to determine what's is or is not happening. Typically the most common cause of failure to join a domain is due to DNS and or NTP issues. If you can perform an adtest command successfully from the CLI then this will rule out those issues.

I would recommend opening an F5 support case so they can further evaluate what is unique about your environment and may be causing your issue.
