Issue connecting / migratinig to new sql database 2012

have a new sql server and was moving the database over to the new sql server.  I am unable to get the installation of the openfire server to actually connect to the new sql server.  it may have something to do with the instance name of the server itself.

so I am at the database settings page of the setup.  the database url.

jdbc:jtds:sqlserver://[host-name]/[database-name];appName=jive

hostname = server5\versitechsql

databasename = openfire

error log reports:  java.sql.SQLException: Unknown server host name 'SERVER5\VERSITECHSQL'.

I have even tried just the server5 and I get connection is refused.

any help would be appreciated.

Thanks
