SQL error, cannot connect to database after restore

I have a database called TVArchive in machine A and there's an service application connects to the database on the same machine.

Machine A crashed, and I built a new one and installed MSDE 2000 and the service application. The database connection from the application was OK.

Then I restored the database backup to machine A's SQL (MSDE 2000). Now when I tried to launch the service application, it says 'cannot connect to database'. I checked SQL logins and database mapping for users, all the same. Is there any database or user identity(such as GUID) that I have change for the restored database in SQL system tables?

The old machine doesn't use ODBC. I checked, there's no ODBC configured.

I deleted user account under database/security and security/login and created the user account and mapped again, but it doesn't work. I think it's mapping issue between the user account and database.

This is because you are not part of the local admin group on the windows server hosting SQL

And you have to have the rights in that database itself in security

Please ignore the image I attached, I figured it's firewall issue when I connect from another machine through SQL Management Studio. But I'm having trouble to connect from an service application to a restored database on the same machine.

the old machine might not use an ODBC but the service application may use one.. did you check that machine the service application is on ?

My thought would be that the service application is looking for that machine or server ID when its making the db connection.

was the service application something created specifically for your business (in house) , customed devleoped outside, or is it a comsumer bought tool ?

It's an application for PBX phone system vendor. It's not widely used. The application version I'm installing is the same version as the old one. The old machine doesn't hava ODBC configured, how it can use ODBC when it's not configured?

You said, machine or server ID, maybe server identity of the application trying to connect to is different than old server.

if its not using an ODBC connection, there have to be some settings somewhere as to how its getting to the database.. those settings are more than likely pointing to the old server

Now I'm trying to detatch and attach to see if it's an issue with restored database

that is a possibility, however your service application (forgive the pun) did not magically know how to connect to that database, there are settings somewhere or a dataconnection sheet.dat file (just an example) that make that connection.

can you give me the exact name of the application
I can possible look up its DB connection properties for you and assist even better :)

Yes, I think it's application issue. I ended up copying tables and now it's working.


Thank you plusone3055 and others.
