See Q164667 in the Microsoft knowledgebase for details ()įor named-pipes over ip 137/138/139 are used. Which ports to open depends on the net-lib you are using :-įor tcp-ip sockets the default port for SQL Server is 1433.įor multi-protocol (rpc) the ports are normally variable, but you can fix them. Under Aliases, make sure the alias you create is for the specific network library your connection string specifies. (You may want to disable/allow all through the firewall during testing to see what extra packets are allowed through). Make sure of two things (both in SQL Server Configuration Manager under the 32-bit and 64-bit SQL Native Client Configuration sections): Under Client Protocols, ensure TCP/IP is enabled. If you've done this and it still doesn't work then look at the firewall logs to see what packets it is dropping or do a network trace either side of the firewall to see what packets are not getting through. You can also use the Client Configuration Utility to add an "Advanced" entry with the appropriate Net-Library and connection string. Configure your firewall server to allow traffic on the specific on the server. Click run and type cliconfg.exe and you will get the utility. This is all what you need to create an alias.

You have to cycle the server after this change.Ģ. Windows ships with the SQL Server Client Network Utility. Make SQL Server listen on a specific port on TCP (the default is 1433) or RPC (the default is a random port greater than 1023).

SolarNetwork is now expanding into a set of tools to not only collect and analyse information, but to also control and influence behaviour of a distributed network of nodes where energy is being generated and/or consumed. You also probably need to check the MDAC version on your client and make sure it's at least version 2.6.

You need to talk to your network team and verify the appropriate ports/paths are open between your client and the SQL Server. Is this because it's behind a firewall? Do they have to open a port for me to connect?One option was to use VPN, but it is slow and I can't use dts to move objects and data back and forth.If this is a firewall issue and the need to open a port, what security issues are there to be aware of?Thanks for any input.

I'm not well versed in security and network infrastructure, so please forgive any novice questions.I setup the server alias name, entered the IP of the remote server in the server name textbox and included 1433 for the port.
Second, when you use an SQL aliase, then you already define the protocol to use in the aliase definition itself this overwrite the general setting. Only if you want to force the client to use always TCP then you have to activate TCP. I am trying to use client network utilities so I can connect to a remote sql server and register an instance on my local sql server.The remote server is on a private company network behind a firewall, which might be why I can't successfully connect.
