IIS 6 running on Windows 2003 with SP2. When I make any changes to IIS's configuration (add a site, change an existing site's settings, etc.) and then restart IIS, all my changes are lost. Uninstalling and re-installing IIS doesn't fix it (yes, I used the SP2 installation disk). Google turns up nothing.
What could be going on? How can I fix this or figure out how to fix this?
