Error code 1726 server configuration
Error: An error occurred during Server configuration.
Cause: This can be due to a temporarily slow network or a heavily taxed computer at the moment of configuration causing the remote installer not to receive the necessary exit codes. Configuration is most likely successful at this point and the displayed error message is simply a response to the exit codes not being returned.
Resolution: Running the configuration wizard again or clicking, I've already manually configured this server under Advanced should result in a successful configuration.
