Node shows an error trying to connect to the SQL server
Running a discovery results in an error showing that the node could not connect to the SQL server.
Confirm you can telnet to the SQL server on the SQL port (default is 1433), using both the shortname and FQDN of the SQL server. If either one fails, confirm there are no firewalls blocking communication and that name resolution is completing successfully. If need be, add an entry in the hosts file on the node for the shortname or FQDN of the SQL server.
