Installed MySQL Server 5.2.22 on a Windows 2008 server. Using the MySQL workbench 5.2 cummunityt edition, the database is working on the server and I can actually log into it via ODBC on the server computer. I have tried to log on the MySQL server on windows 7 client machine using ODBC and it will not see the My SQL server. I have disabled the windows firewall on both the server and the client and I still can not see the My SQL server on the client machine. Openned port 3306 and nothing.
Any suggestions?

Thanks,
Mike

With the ODBC driver, when you try to set up the connection, there should be a test button that you can use before you finish the setup.  What error does it give?

Thanks for the interest. I try to add the ODBC drive MySQL ODBC 5.1 driver version 5.01.08.00 in the client computer and after I enter the connection parameters Data source name, user, password, I can not see any of the databases in the drop down button, and the test fails. (Connection fails: [HY000][ODBC 5.1 Driver]Can't connect to MySQL sever on 'Localhost' (10061). I do the same thing on the server computer and there the databases come up and test is succesfull.

Thanks,
Mike

You can see from the error message that it is connecting to localhost, not the server.  Can you post your connection parameters?

You need to first to configure MySQL to listen for tcp/ip connections.
You the have to use the advanced firewall settings and open the port you configured in the prior to allow access from the private/domain network.

netstat -an | grep 3306
See whether MySQL is using the default port.
Use the MySQL configuration tool to make sure it is configured to listen on tcp/ip.
Then make sure you add the user you want to connect with to allow connections from hosts other than localhost.

Make sure the host parameter is the name of the server rather than localhost, or the IP address of the server.
In addition, you may need to grant permission to the user to allow that database to be accessed from a remote computer, (not on the server as localhost)
Generally speaking the syntax for that type of command is:
grant all on database.tablename to 'user'@'computer or ipaddress' identified by 'password';
tablename could be '*' to specify all tables, and computer or ipaddress could be '%' to specify a user from anywhere.

Using the MySQL workbench on the server I created a new New Connection with the name of the client computers as the user (instead of root). I then tried to create the OBDC from the client computer

 Data Source Name: Mike7 (it is the name of the connection on the server)
TCP?IP Server : 192.168.1.180 (servers ipv4 address)
Port: 3306
User: MIKEWIN7 (name of the client computer)
Password: ****** (same password as server connection)

When I hit the test button : Connection Failed: [HY000][MySQL][ODBC 5.1 Driver]
 Host 'MIKEWIN7' is not allowed to connect to this MySQL server.

How do I give this computer permission to connect. I figured once I created a connection that would be enough to give it permission to connect. I specifically used the name MIKEWIN7 as name of the username on the server New Connection. Im still not there.

Thanks for all the suggestions,
Mike

Within workbench use the administrator.
Then add the user at any host %. Note using the same username at times leads to trouble do to conflict especially if the user has separate password
Usename@client
Usename@%

If you prefer using the comman line interface.

Note that after adding users, you need to flush privileges.

In addition to @arnold's comment, @stpmt11 already gave you the GRANT syntax above.  You can also refer to http://dev.mysql.com/doc/refman/5.1/en/grant.html for more details.

Thanks to all 3 of you. I feel kind of silly for having problem right off the starting gun but you guys helped me connect to the server. I went to the workbech and added users and priviledges. I did it right from the interface.Thanks Arnold, johanntangle, and stpmt11.


Appreciate it,
Mike
