当网站未作为网络服务运行时，应用程序池崩溃

Question

I have a site running Crystal Reports Viewer in IIS 7 but for security reasons we want it to run the application pool under the ApplicationPoolIdentity. We noticed the application pool keeps crashing when we switched it from Network Service to ApplicationPoolIdentity and we want to give extra permissions to the ApplicationPoolIdentity on certain folders on the drive in order to remedy this situation.

The problem is, we gave a ton of permissions to different folders, but as far as we can tell we cannot pinpoint why the application pool keeps crashing and what file it cannot access.

We checked a lot of different log files, but maybe we skipped over some that could be of more importance. Is there anything out there to show us where the problem is, whether it be a certain log I haven't come across or some sort of tracing I can use to get to the files that I need to give this identity permissions?

The pool crashes when trying to load Crystal Reports Viewer and gives no errors, just says it is unreachable.

Answer 1

IIRC Crystal Reports Viewer是一个COM对象...它们通常需要关于权限的特殊情况，甚至可能不可靠，因为某些COM对象需要“桌面”才能正常工作...不确定Crystal Reports Viewer是否是其中之一我建议询问供应商您的方案中需要哪些配置/权限......

Actually you may be able to get this to work by setting the permissions correctly for appPoolIdentity. See the following post on the IIS team blog.
