Hi there,

I try to connect a sql server in my sql management studio but got error msg: "error: 26 Error locating server / instance specified". I can access that sql server through RDP connection and doing some admin jobs there. I am sure the instance name is right ... What should I configure to make it accessible to me? Thanks in advance.

Here is a great article on connection issues. There are some simpler steps in there to confirm access is enabled. Let me know if you have any questions about the steps.

Check if ServerName,PortNumber works in SSMS instead of ServerName\InstanceName.

Or even IP:Portnumber

Another simple thing could be your firewall. RDP already has exceptions to allow remote connections however default SQL might not be allowed. Disable the firewall temporarily and confirm whether access is or isn't there.

Hi guys thanks for the replies. I tried everything possible no luck. I noticed that there are 2 sets of ip used in that sql server so I think it could be the DNS or firewall (not firewall setting in the server) issues.
