HI,

ArrayList lFnGetWebServicesForServer(string aStrServer)

        {

            try

            {

                string lStrIISPath = "";

                ArrayList lArLstFinalServices = new ArrayList();

                lStrIISPath = @"IIS://" + aStrServer + @"/W3SVC";

                DirectoryEntry lObjIIsEntities = new DirectoryEntry(lStrIISPath);

                foreach (DirectoryEntry lObjEntity in lObjIIsEntities.Children)

                {

                    if (lObjEntity.SchemaClassName == "IIsWebServer" || lObjEntity.SchemaClassName == "IIsWebVirtualDir")

                    {

                        System.DirectoryServices.PropertyCollection lObjProp = lObjEntity.Properties;

                        if (lObjProp == null)

                            continue;

                        string lStrTemp = "";

                            lStrTemp = lObjEntity.Name;

                            if (lStrTemp.Trim() != "")

                            {

                                lArLstFinalServices.Add(lStrTemp.Trim());

                            }

                        if (lObjEntity.Children != null)

                            lFnTraceThruChildIISDir(lObjEntity, ref lArLstFinalServices);

                    }

                }

                return lArLstFinalServices;

            }

            catch (Exception)

            {

                return null;

            }

        }

void lFnTraceThruChildIISDir(DirectoryEntry aDTEntry, ref ArrayList aArLstServices)

        {

            try

            {

                foreach (DirectoryEntry lObjEntity in aDTEntry.Children)

                {

                    if (lObjEntity.SchemaClassName == "IIsWebServer" || lObjEntity.SchemaClassName == "IIsWebVirtualDir")

                    {

                        System.DirectoryServices.PropertyCollection lObjProp = lObjEntity.Properties;

                        if (lObjProp == null)

                            continue;

                        string lStrTemp = "";

                            lStrTemp = lObjEntity.Name;

                            if (lStrTemp.Trim() != "")

                            {

                                aArLstServices.Add(lStrTemp.Trim());

                            }

                        if (lObjEntity.Children != null)

                            lFnTraceThruChildIISDir(lObjEntity, ref aArLstServices);

                    }
