We are experiencing the same issue with identical configuration
2008, IIS7, on a Vmware virtual machine). When we recycle the app pool
initial request yields an error. Reloading after the first error
causes the
page to come up normally.

Another note, we applied updates on Nov 15th and noticed the issue
shortly after. Your post seems to be close in terms of dates....

Has anyone else seen this or discovered a solution?
