How to read remote machine event logs - identity issue

I am working on an application to read event logs on a remote machine.  I tried adding this to the web.config
<identity impersonate="true" user="domain\user" password="password" />
However, when I ran this, I got the following error:
Could not create Windows user token from the credentials specified in the config file. Error from the operating system 'Logon failure: unknown user name or bad password.

I looked at this post

It seemed to suggest I would need to create a new account on the remote server.  Is there a way I can just use an existing domain account?
