Question

Hi,
I have created on windows service to fetch sharepoint list ad update the list items.
when i run this service in sharepoint server(where the sharepoint site is hosted),it is working fine. If i run the same service in another machine(sharepoint installed in this machine also). it is giving the below error
The Web application at [URL] could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.
Code snippet
SPSite sharepointSite = null;
            SPWeb rootWeb = null;
            try
                //SPList current = null, previous = null;
                string colmId = ConfigurationManager.AppSettings[ID_COLM];
                List<TaskEntity> list = new List<TaskEntity>();
                sharepointSite = new SPSite(URL);
                rootWeb = sharepointSite.OpenWeb();
                SPList current = rootWeb.Lists[ConfigurationManager.AppSettings[OMEGA_REGISTRATION_LIST]];
                WriteEventLog("current" + current.Items.Count.ToString());
            catch (Exception ex)
                ExceptionMethod(ex);
            finally
                sharepointSite = null;
                rootWeb = null;

Hi mallela1,
I also had similar issue couple of months back when I was trying to access a remote URL from a Windows service when the site does not exists in the server where service resides.
You cannot access a remote url (even though it is SharePoint server and also in same network ) from server object model.
SPSite can look in the current server only. here what is happening is SPSite will look for this in the current server DB and it is not finding this errror.
So please dont use ServerObject model for accessing remote sites. You can use Client Object model for the code /requirement you have stated above.
I wasted lot of time in finding a work around to make to work. It did not. So look for other options.
