Version 706 is a database file from Sql Server 2012
Version 665 is a database file from Sql Server 2008R2 (post SP1 ?)

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

如果您尝试连接到本地数据库，请使用LocalDb（自vs2012，sql2012），即： 

Data Source=(LocalDB)\v11.0;AttachDbFilename= (etc)

I'm sure the problem was that aspnetdb.mdf can't open.

Sometimes this file gets corrupted. The problem was that I can't validate login page.

After deleting(and replacing) my login form control, the problem was solved.

The reason for this was because control from asp.net uses aspnet membership. I replaced my login control (with javascript) with CSS style and remove all related files and that solved it.

I hope this helps someone.
