Can you RDP onto the remote machine?

If so, can you confirm that the instance is running OK? If so, is it accessible when logged on to the remote machine? (e.g. if you have management studio installed on the remote server, can you connect to the instance using (local) )

If all that looks good, then you've confirmed that the SQL instance is running OK and it's likely to be some sort of network problem between you and the server

When connecting to the remote server, are you using a domain name or IP? e.g MYSQLSERVER05 or 172.88.16.254

If you are using Domain Name, try connecting using IP. Can you connect? If so, it's some sort of DNS issue.

See how you get on with that & we can narrow it down further

Make sure it's configured to allow remote access.

Perhaps there's a firewall involved? You may have permission to ping it but the sql server port may not be in the allowed list. If so, you may need to configure the firewall to allow incoming connections on the sql server port.

Take alook, may be there is something helpful info for you.

Potential causes of the "SQL Server does not exist or access denied" error message[^]

You may not be able to connect to an instance of SQL Server that is configured to use the TCP/IP server network library on a computer that is running Windows XP Service Pack 2[^]
