在 Episerver 项目中，从一台服务器上的网站调用另一台服务器上的 ASMX-webservice。调用的用户有权在 IIS 7 中设置写入、创建和检索文件夹中的文件。
进行此调用时会出现以下错误消息：
RemotePublishForLedigeStillinger.DataFactoryService.RawPage rawPageLedigeStillingerRemote = dfService.GetDefaultPageData(pageRef, Int32.Parse(pageidOfLedigeStillingar));
如何解决以下错误？：

补充：用户是'dr-2\epi-admin'。
它的登录详细信息被发送到服务器：
