If World Wide Web Publishing Service (W3SVC) starts before Microsoft Exchange Information Store (MSExchangeIS), "stop sign" symbols appear under the Default Web Site folder of the Internet Information Services console in Microsoft Management Console (MMC).

There is a dependency between the local paths of the SharePoint Portal Server virtual directories and the MSExchangeIS. You must start MSExchangeIS first, followed by W3SVC.

Complete the following steps to prevent the stop signs from appearing each time you restart:

# Change the Startup type for W3SVC to Manual.
# Restart the server. The MSExchangeIS service starts automatically.
# Start W3SVC.
