Can't connect to SQL Server I'm trying to set up Peer-to-Peer Transactional Replication and I'm stuck at "Add a New Peer Node" step - I can't connect to another server.

In server name field I specify serverIP\DBNODE2 and SQL Server credentials.

I'm 100% sure that the credentials are correct, but I'm not sure about the server name part.



When I try to connect I get the following error:



Any ideas what am I doing wrong?

EDIT: I've checked:


Started SQL Server Browser service
SQL Server service for MSSQLSERVER is running
Firewall is off
Remote connections are enabled in Configuration Manager
TCP ports are enabled


Server name is DBNODE2.
SQL Server instance name is MSSQLSERVER.

The only thing, that I don't understand why it's asking server name? This server is in remote geographical location, so I don't think, that it could find the right server without IP address.
I've tried bunch of different combinations and none of them worked:


IP\DBNODE2
IP\MSSQLSERVER
DBNODE2\MSSQLSERVER
IP
DBNODE2
Also tried double backslashes
Etc.


EDIT2:
SQL Server service is running under 1433 port.
I've used Port Query tool, which I've found here.

ANSWER: Probably server IP address is not allowed in server name field. The workaround is to modify hosts file like @MarkIannucci decribed below.
If your server's ip address is static, you can modify your hosts file with a reference to DBNODE2's ip address and specify DBNODE2 in your Connect to Server Server Name file.
