&“无法打开源日志"-Windows 7-.NET Web服务-事件日志 [英] "Cannot open log for source" - Windows 7 - .NET web service - event log

问题描述

我有一个试图登录Windows事件日志的.NET Web服务.但是，当我尝试向该Web服务中的Web方法发送SOAP请求时，我在SOAP响应中得到了以下错误:

I have a .NET web service that is trying to log to the Windows Event Log. However, when I try to send a SOAP request to a web method in this web service, I get back this error in the SOAP response:

System.InvalidOperationException:无法打开源"MySource"的日志.您可能没有写权限.---> System.ComponentModel.Win32Exception:访问被拒绝

System.InvalidOperationException: Cannot open log for source 'MySource'. You may not have write access. ---> System.ComponentModel.Win32Exception: Access is denied

我已经尝试了Google搜索以寻求解决方案.这个介绍了如何编辑Windows 7 64位版中不存在的注册表项；与此Microsoft页面相同.这个问题是相关的，但唯一的答案它谈论的是源"键，该键似乎不在HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ eventlog \ MySource中的任何位置.如果我需要添加Source键，那么它的值应该是多少?我在Web服务的Web.config(< identity impersonate ="true"/> )中使用模拟.这个问题也相关，但没有答案.此问题与但同样，它的答案似乎与Windows 7中的注册表设置无关.

I've tried Googling around for a solution. This one describes editing a registry key that does not exist for me in Windows 7 64-bit; same for this Microsoft page. This question is related but the only answer to it talks about a 'Source' key that does not seem to be anywhere in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\eventlog\MySource. If I need to add a Source key, what does its value need to be? I am using impersonation in my web service's Web.config (<identity impersonate="true" />). This question is related as well but has no answers. This question is related but again its answer doesn't seem to pertain to the registry setup in Windows 7.

我在Web.config中同时设置了<身份验证模式="Windows"/> 和 .但是，即使删除< authentication mode ="Windows"/> ，我仍然会收到无法为源打开日志"错误.

I have both <authentication mode="Windows" /> and <identity impersonate="true" /> set in my Web.config. However, even when I remove <authentication mode="Windows" />, I still get the "Cannot open log for source" error.

推荐答案

我的经典ASP Web应用程序在Windows 7 64位中遇到了完全相同的问题.我最终发现，通过将该网站的应用程序池更改为启用32位应用程序"(右键单击应用程序池，高级设置)，问题消失了.

I was having the exact same problem in Windows 7 64 bit for my classic ASP web application. I eventually found that by changing the application pool for that website to "Enable 32-bit Applications" (right-click application pool, advanced settings) the problem disappeared.
