After moving an IIS 6 / .Net 2 app to IIS 7.5 - it seems that after I update the website then stop/start IIS it takes forever (almost an hour) for IIS to start serving content again. I've tried various methods of stopping/starting IIS as well as IISreset /noforce but nothing works. Even after a reboot the website just spins. Then after a while it just start working again.
The trick is that this only happens on servers in one environment. All others work fine and respond immediately after a app pool recycle is issued.
Any tips / suggestions as to where I could look to find a difference or cause???
