I thought there is some problem in connection Strings but for me everything looks fine, and my question how to fix this problem?

Version 706 is a database file from Sql Server 2012

Here is Tested Solution, 1st Connect both Server in your SQL Server Management Studio and then RUN the 1st Code Block
--1st Run this (One Time)
EXEC sp_addlinkedserver
@server='YOUR_SERVER_IP', -- here you can specify the name of the linked server
@srvproduct='',
@provider='sqlncli', -- using SQL Server Native Client
@datasrc='YOUR_SERVER_IP', -- add here your server name
@location='',
@provstr='',
@catalog='DATABASE_NAME'
Then Run this Individually
SELECT TOP(100) *
FROM LOCAL_TABLE A, [YOUR_SERVER_IP].DATABASE_NAME.dbo.TABLE_NAME C
WHERE A.ID=C.ID
