This should work for you. You need to specifiy the domain controller server name including its domain name in full. The following code should make things alot clearer. DirectoryEntry de= new DirectoryEntry(); de.Path = "LDAP://clown.acme.com"; //clown is the server name hosting the domain controller & acme.com is the domain name. de.Username = "administrator"; de.Password = "passw$rd"; de.AuthenticationType = AuthenticationTypes.Secure //now lets search for a user using the above credentials try { DirectorySearcher searcher = new DirectorySearcher(); searcher .SearchRoot = de; searcher .Filter = "(cn=" + "Domin Admins" + ")"; SearchResultCollection results = searcher .FindAll(); Console.Writeline(results.Count.ToString()) } catch (Exception exception) { Console.Writeline(exception.Message); }

Hello, Sorry, haven't looked into it before given you the advice! All the best, Martin

this.myDataGrid.DataSource = myDataSet; only the first datatable of the dataset will be assigned to the datagrid if we use the above syntax. But i have to use the datarelation of the dataset. what should do for that? thanks a lot for your response. thanks in advance

The question is a bit short to really understand your problem. But I will try to guess here. The most basic operation to be able to use a webservice in your application is to right-click on the project and choose Add Web Reference. There you browse to the webservice, give it a good name and select OK. After that it's just simply a matter of doing something like this: ServiceClass service = new ServiceClass(); object someResult = service.SomeMethod(someParameter); The service class is strongly typed, so you shouldn't have much trouble finding out how to call the service and what to pass and what you get in return.
