ASMX (OOTB SharePoint Web Service) reference in Custom web part

Question

I have created a web part that consumes socialdataservice.asmx. For this I created a web reference to socialdataservice.asmx and creatd a proxy "socialservice".

In the code;

                            socialservice.SocialDataService proxy = new socialservice.SocialDataService();
                            proxy.PreAuthenticate = true;
                            proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
                            socialservice.SocialTermDetail[] tagDetails = proxy.GetTagTermsOnUrl(webURL, 50);
                            string[] users = new string[100];

This code is working fine in my DEV but when I moved this to QA - Its causing the following exception

"Server was unable to process request"

how to resolve this?

Thanks

My reference.cs file contains the following code where the url points to server:6000 root site collection

        public SocialDataService() {
            this.Url = "http://server:6000/_vti_bin/socialdataservice.asmx";
            if ((this.IsLocalFileSystemWebService(this.Url) == true)) {
                this.UseDefaultCredentials = true;
                this.useDefaultCredentialsSetExplicitly = false;
            }
            else {
                this.useDefaultCredentialsSetExplicitly = true;
            }
        }

I was wondering how to make it generic that will help us to point to the dite collection where the web part is installed?

Ya normally in your code along with PreAuthenticate and Credentials, you'd set the Url property to the path to the asmx file, something like SPContext.Current.Web.Url + "/_vti_bin/socialdataservice.asmx";
