IP Address has recently been changed on the server. We have used a number of different application to access the SQL Server. Using data source and applications such as Marsc now cannot access the server.
Any suggestions of what the problem is. Have ensured all the port numbers etc... are correct but still no luck and we have come to a brick wall dead end!
This doesn't appear to be a firewall issue on our side. We are only assuming it is most likely an issue with SQL Server itself or firewalling on the InterXion side of the link.
