Event log access problem with ASP.NET

[Phil Turtle]

We're using the Application block for publishing exceptions from our web
site using the default publisher which writes to the event log. This works
fine on XP and on one of our dev. machines running Windows 2003. However we
now have a problem on a test machine with Windows 2003 where we get a
security exception because the process doesn't have access to the event log.
The only difference I know of is that the test machine has Windows 2003 SP1.
On both W2003 machines IIS6 is running under the default account which
supposedly has access to the event log resource.

Has anyone any ideas of how to solve this? Is it due to a change in the O/S
service pack?

(We are using .NET 1.1)

Hi,

you have to create the event source first, this has to be done from an account
with administrative privileges.

EventLog.CreateEventSource(..);

Hi, make sure the account running the application pool that your web
application is using has access to:
"HKLM\SYSTEM\ControlSet001\Services\EventLog". As default
application pools are running as network service, that don't have
access to this key.

Does anybody have any real solutions to this problem?

Hi,

as stated before - the asp.net worker process does not have the required
rights for the registry key

you have two options:

a) change the ACL
b) pre-create the EventSource using a console helper that is run by an admin
- ASP.NET will be able to use the event log afterwards

 

[Phil Turtle]

As I stated before this is NOT the problem. The Event source already exists.
It is NOT - repeat NOT - a registry permission problem

Hi,

so can you show us the exception details with full stack trace?
