Administering an ISP Installation

Administering Older Version Servers

This section tells you how to use the IIS snap-in to administer servers running previous versions of IIS. (Previous versions are also referred to as downlevel versions.)

If, for example, you have five Web servers running IIS 3.0 and you initially upgrade one of them to IIS 5.0, you can administer all of them from the IIS snap-in.

To administer older version Web servers

1. Create a temporary folder.

   This folder lets you rename the files that you copy in step 2, so that you don’t overwrite existing files (that currently live in your C:\WINNT\System32\Inetsrv directory) with the same name.

2. From the Windows 2000 Server CD, copy the following files into the temporary folder you have created:

   File Name	Directory Location
   Fscfg.dll W3scfg.dll Gscfg.dll	\I386\inetsrv\
   Fscfg.hlp W3scfg.hlp Gscfg.hlp	\I386\inetsrv\help\

   
   
3. Rename the files in the temporary folder. For example:

   Old Name	New Name
   Fscfg.dll	Fscfg3.dll
   W3scfg.dll	W3scfg3.dll
   Gscfg.dll	Gscfg3.dll
   Fscfg.hlp	Fscfg3.hlp
   W3scfg.hlp	W3scfg3.hlp
   Gscfg.hlp	Gscfg3.hlp

   
   

   The Gopher DLL (Gscfg.dll) does not have to be renamed, but this has been done for consistency.

4. Copy the renamed files into your C:\WINNT\System32\Inetsrv directory.
5. Add the following registry values (with data type REG_SZ) to

   HKEY_LOCAL_MACHINE
   \Software
   \Microsoft
   \InetMgr
   \Parameters
   \AddOnServices

   WWW3 = C:\WINNT\System32\inetsrv\w3scfg3.dll::SUPCFG:C:\WINNT\system32\inetsrv\w3scfg.dll
   FTP3 = C:\WINNT\System32\inetsrv\fscfg3.dll::SUPCFG:C:\WINNT\system32\inetsrv\fscfg.dll
   GOPHER3 = C:\WINNT\System32\inetsrv\gscfg3.dll
   

   Caution   Do not use a registry editor to edit the registry directly unless you have no alternative. The registry editors bypass the standard safeguards provided by administrative tools. These safeguards prevent you from entering conflicting settings or settings that are likely to degrade performance or damage your system. Editing the registry directly can have serious, unexpected consequences that can prevent the system from starting and require that you reinstall Windows 2000. To configure or customize Windows 2000, use the programs in Control Panel or Microsoft® Management Console (MMC) whenever possible.

   This step appends “::SUPCFG:<newer dll>” to the existing DLL file name, indicating that the current files have been superseded.

6. From the IIS snap-in, connect to a server running IIS 3.0. To do this, open the IIS snap­in, select Internet Information Services, click Action, then click Connect. Enter the name of the Web server you want to connect to.

At this point, you can see the Web server from the IIS snap-in.

The Properties toolbar button in the IIS snap-in is not available for some older sites. Instead, you must right-click the name of the site and select Properties. You can also select Properties on the Action menu.

The following figure shows the IIS snap-in connected to a server (called “someone”) that is running IIS 3.0.
