SP 2013 - Error: This operation can be performed only on a computer that is joined to a server farm

Question

Hello Community!
I am working with SharePoint 2013 and I built a farm inside the firewall.  Then a decision was made to move the two WFE's to the DMZ.  Since that time, whenever I try to access the site collections, I get the error below.  Other information: All
the web applications are on port 80, but I'm not having any problem with accessing Central Administration which is on port 8080; the network team did screw up the DNS originally, but I'm told it's correct now; the two WFE's servers show in my Manage servers
on the Farm interface 2X, once with the server name, once with the fully Qualified Domain Name, the ones with the FQDN shows a Services Running status of Not Configured.
Has anyone else ever seen this error and if so please provide guidance and instruction for fixing the error.
Thanks!
Tom

Hi Tom,
According to your description, my understanding is that you got an error when you moved your SharePoint.
This error occurs when the SharePoint farm administrator cannot connect to your configuration database. Please verify the followings:
Make sure that from the SharePoint front end and application servers that you can ping your SQL server.
Make sure that your Farm account has permission to the configuration database.
Lastly verify that your database didn't for some reasons go into recovery mode.
once everything is fine and you are still having issues, restart the SQL host service on the SQL server. Once the service is restarted you will need to reboot Central Admin and then your front end servers.
In addition, as you built your farm inside the firewall, please disable the firwall, or create rules for SQL Server service in the firwall on SQL server. More information about creating rules in firewall, please refer to the following posts:

I hope this helps.
