SUS will disable parent paths and ASP sessions state.

With these disabled you will get "HTTP 500.100 - Internal Server Error -
ASP error
Internet Information Services"

Microsoft recommends that the IIS server host only SUS. Although this is
not a requirement, it is a good idea because installing SUS locks down your
IIS server by installing URLScan. The WebDAV, Internet Printing, and
Indexing service features of IIS are turned off. Also, the session state is
disabled by SUS. When the session state is disabled, ASP cannot create a
session for each user who accesses an ASP program, and ASP scripts cannot
store information in the Session object or use the Session_OnStart or
Session_OnEnd events.
