BTW: This is the second time I am attemping to post this post. If I am doing something wrong please let me know.

After installing Windows Critical Updates to our Windows Server 2003 SP1 running dotnetnuke 4.3.4, IIS 6.0, all attempts to access dotnetnuke pages result in:

404 "This page cannot be found".

From the System log:

I took a look at the logs and noticed an error:

It seems to be a dotnet application pool crash issue.

Anyone seen this before?
