At the moment I am only working with SQL-A, SQL-B, SQL-CORE and DC
Question 1: Up until about 3 hours I could connect remotely from SQL-A to SQL-B, now I am getting a network related error, when I turn off the firewall on SQL-B I can connect fine. When I first set up the rule and installed SQL Server I had the same issue but after leaving it for a few hours I could connect, I put this down to the firewall rules not being applied immediately. Now I am at a loss, it was working correctly, now it isn't, has anybody got ideas?
Question 2: I have also installed SQL Server on SQL-CORE, I have not been able to connect remotely even if I turn the firewall off. I have a very little previous experience of Server Administration so I am struggling to grasp Server Core, I am mainly using MMC to manage the firewall rules through another machine. I can see the program rule I have created on the firewall though, has anybody got any ideas on how to troubleshoot this issue?
I have spent quite a lot of time trying to figure this out, at least a week now so if you have any guidance I will appreciate that, if you can provide a list of what SQL Server uses for remote connection and how I can troubleshoot it that would be extremely beneficial.
I was hoping to have the material covered quite quickly but this is really putting a roadblock in the way, I have gone further through the material as I have an instance on my host machine that I can use but I cannot carry out a lot of the training exercises.
Thanks
