Failed to validate the user credential, configuring ethernet interfaces

    Hi edwardd 

    Another thing to check/ask - is the appliance configured to use Active Directory (or LDAP) authorization/authentication? If so, you could try removing this (you can reconfigure this later once the network is functioning again). 

    Also, if you are able to log in and can get an elevated shell running, you could try renaming the /etc/resolv.conf file to see if this helps you configure the network correctly.

Hi davidmoline,

To reply back to your previous posts:

  1. Combined master and media server (well, it's just a single server/appliance I am working with).
  2. Thank you for providing insight on the slow boot time. I guess in the future, it may have been best to unconfigure all network/ethernet interfaces first?
  3. Active Directory/LDAP is not configured on this appliance.

I will have to attempt the elevated shell to try to get some recovery operation going, likely with the assistance of support.

Hi edwardd 

I been involved in moving appliances before (not many though) and not encountered problems such as yours. I don't recall having to do anything specil before moving the appliance and simply reconfiguring the interface in the new location. I hope it can be as simple as disabling name resolution temporarily to enable you to config the network correctly. 

If you are able to get an elevated shell it is worth trying, but otherwise work with support to resolve your issue.

    Hi davidmoline. I wanted to provide an update on the situation. The sluggishness and errors specified were remediated as soon as I renamed the resolv.conf file (via an elevated Maintenance prompt). So, the behaviors did seem to be related to DNS reverse lookups. The network interfaces configured just fine afterwards as well.

    To anyone that encounters this thread, and the behaviors are similar and/or consistent with the original post, hopefully disabling name resolution (by renaming resolv.conf) restores functionality to your appliance.
