Question

我有一个完全可以从localhost运行的web服务，但是当我在测试服务器上托管它时，我得到了其中一个方法的错误。我正在使用wsHttp绑定。除了这个方法之外，其他一切在客户端都能正常工作。这是我得到的错误

客户端错误：

System.ServiceModel.Security.SecurityAccessDeniedException: Access is denied.

Server stack trace: 
   at System.ServiceModel.Channels.ServiceChannel.ThrowIfFaultUnderstood(Message reply, MessageFault fault, String action, MessageVersion version, FaultConverter faultConverter)
   at System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime operation, ProxyRpc& rpc)
   at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout)
   at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)
   at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

服务器错误：

namespace.Service Error: 10001 : Error occurred in methodname(). 
 System.Security.SecurityException: The source was not found, but some or all event logs could not be searched.  Inaccessible logs: Security.

   at AutoWatch.Entity.WcfService.TrackingService.GetNewIncidentMessage(String username) in C:\..servicename.cs:line 444

失败的程序集区域是：我的电脑

我在服务器上收到的错误中添加了。我是否有可能收到此错误，因为该服务无法写入事件日志？

请帮忙。

确保运行托管服务的进程的帐户具有对数据库的访问权限。例如，在IIS的情况下，运行托管服务的应用程序池的帐户必须登录到数据库服务器，并且它必须具有在数据库中执行所有必要操作的权限。

编辑：

服务器堆栈跟踪看起来非常简单。写入Windows事件日志时遇到问题！它无法找到您请求的来源，也无权创建它。

Web服务中的方法的访问被拒绝错误
