but when i try to run it into machine that is currently logged-In into our domain it does not have any problem. but i want my windows application to work on both either under the domain or not.

            //List_Service is one of my Web References which is referenced to
           //Sharepoint List Service
            List_Service.Lists myservice = new List_Service.Lists();
            
            // Authenticate the current user by passing their default 
            // credentials to the Web Service from the system credential 

            myservice.Credentials = System.Net.CredentialCache.DefaultCredentials;

            // Declare an XmlNode object and initialize it with the XML 
            // response from the GetListCollection method.
            
            System.Xml.XmlNode node = myservice.GetListCollection();

            // Loop through XML response and parse out the value of the
            // Title attribute for each list.
            foreach (System.Xml.XmlNode xmlnode in node)
            {
                txtUsername.Text  += xmlnode.Attributes["Title"].Value + "\n";
            }

any input will be greatly appreciated...thanks in advance!

Your problem is where you set the service credentials (myservice.Credentials).
System.Net.CredentialCache.DefaultCredentials retrieves the currently logged in (i.e. thread principal) account - this account must have rights on SharePoint, and if you're not on the domain, I believe you'll find that (in the Security event log of your SPS server) there are either several failure audits, or an anonymous login.

Hazarding a guess - haven't come across a situation like this in our projects - you may be able to allow anonymous users access to the specific area or web: if you can, would suggest giving them reader rights.

A last resort would be to wrap the SharePoint web-service with one of your own, i.e. a web service calling a web service: your web-service will allow anonymous calls, and will impersonate a configured user to call the SharePoint services.

what if the the account of the User has rights on sharepoint but he/she is not on the domain is it posible for the application to just prompt the user for his username, domain and password and use it instead of the defaultcredentials.

[axion_sa]

Not sure if it'll work if one is not on the domain, but it's worth a check:

myservice.Credentials = new NetworkCredential("Username", "Password", "Domain"); // Assuming I remember the order of parameters correctly...
myservice.PreAuthenticate = true;

will anybody help me with this..I copied the code below from Microsoft Windows Sharepoint Services SDK but it juts wont work everytime i execute that code can anybody body please tell me whats wrong or is there something i missed in that code..by the way the error in the code below happens in this line

System.Xml.XmlNode nodeListItems = listService.GetListItems(listName,viewName,query,viewFields,rowLimit,queryOptions);

            // Declare and initialize a variable for the Lists Web Service.

            credentials to the Web Service from the system credential cache.*/
            listService.Credentials = System.Net.CredentialCache.DefaultCredentials;

            // Set the Url property of the service for the path to a subsite.
            listService.Url = "http://sharepoint/_vti_bin/Lists.asmx";

            // Instantiate an XmlDocument object
            System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();

            // Loop through each node in the XML response and display each item.
            foreach (System.Xml.XmlNode listItem in nodeListItems)
            {
                label1.Text += listItem.OuterXml;
            }
