在Vista中使用C＃VS 2008为SQL Server 2008创建用户组时出现错误号2202

Question

I'm trying to create user group for registered in SQL Server 2008.

This is my code :

[DllImport("Netapi32.dll", CharSet=CharSet.Unicode)]
internal static extern int NetLocalGroupAdd([In, MarsharAS(UnmanagedType.LPWStr)]     string serverName,[In] int level, [In] reg NativeHeaders.LOCALGROUP_INFO_1 info0, out int     paramError);

internal struct LOCALGROUP_INFO_1
{
    public string lgrpi1_name;
    public string lgrpi1_comment;
}  

$ always return error number 2202( User name not valid )
Public void CreateWinAuthGroup ()
{
        var localgroup_info_ = new LOCALGROUP_INFO_1
        {
            lgrpi1_name = "TesUserGroup",
            lgrpi1_comment = "Group for My Application"
        }
         int error = NetLocalGroupAdd(serverName, 0, ref localgroup_info_, out paramerror);

}  

Has anyone else faced this issue? This source running well on my standalone test application. But always returns error when integrated with main application.

Thanks for any help.

Answer 1

Found the error.it's because I doing testing using my custom string group user name. so it will be running well. but on real class, error is because username group format not valid. error 2202 is : error number description for Terminal Server . So the problem is closed.
