remote connection to SQL server issue

Im using SQLAPI++ to connect unmanaged c++ to sql.  On local machine works perfect. I can get as many instances open as I need all looking at the SQL, all connections fine.

I then setup sql server 2008 to handle remote connections by enabling  Named Pipes in the configuration manager and restarting as I learned by default it doesnt allow remote connections.

from another machine i want to connect to the database.  I can ping the server CAVIARIS  the code sees the server but the logon fails?  I dont have any passwords, its windows authentification, I dont care about what authentification it has to be so if I need to change tell me.  

It fails by saying Logon failed for user CAVIARIS\Guest  

I want a number of machines to connect to SQL but Im stuck on the connections.  Do I have to do something in Serrver Management studio?  ie do I have to create a logon before I can go to the client machine and logon, is that the basic philosophy of how this works?  

I need a generic logon for any machine that accesses SQL database, Im hoping I dont have to manually create a new one each time as Im trying to make a cluster of servers all see the same database.  Can someone please walk me through a procedure to get me connected.  its XP  machines are in a network workgroup configuration.

Ive tried scores of combinations but I think Im missing a more general point, thanks

Yes you have to do something in SQL Server Management Studio.

You need to create a SQL Login. The SQL Login can use SQL Authentication or Windows Authentication, and in the last case be a Domain User or Domain Group.

The login then needs to be mapped to a user in a database, and given rights to that database. If you use a Domain group, this is a once per new server per new database - then might need some maintenance/adjustment etc.

I think I may already have done the first part.  I created the database in VS 2008.  When I open the datbase in Server Management Studio I can see the login details
Server Type: Database Engine
Server Name: CAVIARIS
Authentification: Windows Authentification
User Name: CAVIARIS\Administrator
No password.

how do you you map the login to a user in a database and give them rights?

In SSMS Query Explorer, go to the database in question, navigate to security and users, right-click and select New User.

You will see other users already there.

I suggest to get started that you ned to make this user a member of db_datareader.

EVERY object will need rights assigned, and while this can be done at the schema level in SQL 2005 and above, it will still need to be done. Please do avoid the temptation of simply making the new user a member of dbo. This is not the sort of permissions you want an ordinary user to have.

You need to start the SQL Browser service and enable named pipes

OK Ive been a few hrs into this, heres where Im at.  With the help of the last post I have managed to get remote connections operational.  I thought I did this with reading from internet and enabling TCPIP but that was only half the story I didnt know about the server browser, so thats all operational now.  

From another machine I can ping the server.  I discovered something called a log file viewer where I can see why the client wont connect.  I have an error message and have looked at the help but Im baffled by what to do?

Error 18456 Severity 14 State 11.  Token based server validation failed with an infrastructure error.  So reading the help it says I do not have permission to login to server.  OK

How do I give myself permissions to loginto my server?

I right clicked on guest -> properties and clicked on every single button to see if thats it but im unsure and maybe causing more drama than just asking you guys?
