unable to connect to the remote server web service sharepoint

 Hi,

i am using sahrepoint webservice for getting document from another sahrepoint site.my source server is wss3.0

and my destination server is moss2010.

i wrote code like the below.

                 WSCopy.Copy copyService = new WSCopy.Copy();

                copyService.Url = http://server:8080+ "/_vti_bin/copy.asmx";
             
                copyService.Credentials = CredentialCache.DefaultCredentials;

                 WSCopy.FieldInformation fieldInfo = new WSCopy.FieldInformation();
                WSCopy.FieldInformation[] fieldInfoArray = { fieldInfo };
                WSCopy.CopyResult cResult1 = new WSCopy.CopyResult();
                WSCopy.CopyResult cResult2 = new WSCopy.CopyResult();
                WSCopy.CopyResult[] cResultArray = { cResult1, cResult2 };

                    byte[] fileContents = new Byte[4096];
                copyService.GetItem( "http://server:8080/shareddocuments/sample.doc" , out fieldInfoArray, out fileContents);
