Odbc Sql Server

Hello,

My name is Franklin my problem with SQL Server is the next I create a Windows group to access SQL Server in this way I just need to give access to the group not all the people on it, the problem is that work on a Windows Server 2003 but does not work in Windows XP SP2, any help? Thank you in advance

The error in XP is as follows:

[Microsoft] [ODBC SQL Server Driver] [SQL Server] The name supplied (username) is not a user, role, or log-aliasing.

Your XP computer users can use builtin, if not to join a domain, you must define groups BUILTIN groups that your XP does not recognize domain users or groups.
Hope this helps.
