Is the web server with IIS 6.0? If so, you need grant permission to the
NETWORK SERVICE account. You may temporarily add this account to local
administrators group to see if it will help. If so, it will still be a
permission issue. I suggest you may trace the registry and file access with
two utilities: regmon and filemon. They can record any access to registry
and files. With them we can found what cause the access denied error. You
can found free download these two utilities: [url]www.systeminternals.com[/url]

Thanks Luke. I discovered that it is not a permission problem afetr adding
the n/w service a/c to the administrators group. I deleted and recreated the
custom event log and it worked fine.

Thanks one again.
