Upgrade to IIS 4.0 May Give Extra Virtual Directories (187738)
The information in this article applies to:
- Microsoft Internet Information Server 4.0
This article was previously published under Q187738 We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site: SUMMARY
After an upgrade from Internet Information Server (IIS) 1.0, 2.0, or 3.0
on a computer with multiple virtual servers, you may find that you have
extra virtual directories under each server that were not defined under
the previous version.
MORE INFORMATION
Under IIS 1.0, 2.0, and 3.0, a virtual directory could be defined without
an IP address. This virtual directory was considered "global" for all
servers on that computer. Under IIS 4.0, this is no longer the case, and
all virtual directories must be explicitly defined for each Web server.
During the upgrade process, if the Setup program notices that the server
has a "global" virtual directory, Setup adds the virtual directory to each
of the Web sites on the computer, because there is no way to determine
which server the original virtual directory was defined for.
