One MS SQL Svr connects great, the other one does not.  What should I check/compare between the 2 ???

1> exit

C:\Documents and Settings>sqlcmd -S SQLSVR02 -Uuser1
Password: Msg 18456, Level 14, State 1, Server SQLSVR02, Line 1

Does user1 exist in SQLSVR02 ?
Your problem most likely is somewhere within the connection string. A couple options to try would be copying the connection from the working database and then editing bits of information such as the table name and cells.

If you're devloping locally and then uploading to a server, perhaps using Microsoft's Visual Web Developer, often the web.config file will be pointing to wherever the database file was located for development. This is where Web Developer tries to help just a little too much in order to make sure your site / application can find the database.

For example:
        <add name="Connection Database" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Documents and Settings\user\Desktop\database\DATABASE.mdf;Integrated Security=True;User Instance=True"
            providerName="System.Data.SqlClient" />

Should look something like this...
        <add name="Connection To Database" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\DATABASE.mdf;Integrated Security=True;User Instance=True"
            providerName="System.Data.SqlClient" />
        <add name="Connection To Database" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=DATABASE.mdf;Integrated Security=True;User Instance=True"
            providerName="System.Data.SqlClient" />

by looking at the SQL Server Logs, I was able to get the following specific error:

From the MSSMS Go to Management -> SQL Server Logs

04/16/2010 16:26:23,Logon,Unknown,Login failed for user 'user1'. Reason:
An attempt to login using SQL authentication failed. Server is
configured for Windows authentication only. [CLIENT: <local machine>]
04/16/2010 16:26:23,Logon,Unknown,Error: 18456<c/> Severity: 14<c/>
State: 58.

I needed to add SQL Server Authentication.  This is done by
1. Right click on the Server
2. Select  Properties
3. Select Security
4. Change Radio Button from Windows Authentication Mode to SQL Server
and Windows Authentication Mode
5. OK
6. Restart the SQL Server - this can be done by right clicking on the SQL Server and selecting the Restart option
