   Q256986 Description of the Microsoft Windows Registry

SUMMARY
=======

After you install the Microsoft Exchange Active Server Components, the default
Internet Information Service (IIS) 4.0 virtual directory for accessing the
Outlook Web Access (OWA) logon page is set to "/Exchange".

Under certain circumstances, you may need to change this.

MORE INFORMATION
================

Use the following steps to change the current virtual directory.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems
that may require you to reinstall your operating system. Microsoft cannot
guarantee that you can solve problems that result from using Registry Editor
incorrectly. Use Registry Editor at your own risk.

NOTE: Make copies of all files before making any changes!

1. In the <Exch_dir>\Webdata\Global.asa and
   <Exch_dir>\Webdata\<Lang>\Constant.inc files, change bstrVirtRoot
   = "/exchange" to bstrVirtRoot = "/<new_virtual_root>", substituting
   your new name for "<new_virtual_root>".

   NOTE: Always use lower case for anything that might find its way into a URL.

   IMPORTANT: If you ever change something in the Global.asa file, you must also
   make a matching change the Constant.inc file. The two files contain some
   duplicate data that must be kept synchronized.

2. In the following registry key, change the registry setting that the Exchange
   Filter (Exchfilt.dll) uses:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\Applications\<key>

   Where <key> currently = Exchange. Change the value <key> to =
   <new_virtual_root>.

3. In the <Exch_dir>\Webdata\<Lang>\Default.htm file, change

   <META HTTP-EQUIV="REFRESH" CONTENT="0; URL=/exchange/logon.asp">

   to

   <META HTTP-EQUIV="REFRESH" CONTENT="0; URL=/<new_virtual_root>/logon.asp">

   Search the <Exch_dir>\Webdata\<Lang> folder and subfolders for any
   other *.htm files containing the string "/exchange". Replace the text as
   above.

4. In the
   <Exch_dir>\Webdata\<Lang>\Forms\Ipm\Schedule\Meeting\Request\Mrread.asp
   file, replace all occurrences of "/exchange" with "<%=bstrVirtRoot%>".

   Search the <Exch_dir>\Webdata\<Lang> folder and subfolders for any
   other *.asp files containing the string "/exchange". Replace the text as
   above. The Tshoot.asp file may safely be ignored.

5. Using the Internet Service Manager on the IIS 4.0 computer that is configured
   with OWA, locate the "Default Web Site". Within the Default Web Site, rename
   the "Exchange" application to the name of your <new_virtual_root>.

After you make this change, you will need to enter
http://<server>/<new_virtual_root> to access the Outlook Web Access
logon page.

Also, you can add more keys to the Applications key, and the Exchange Filter will
do language switching for those virtual roots as well.

NOTE: Whenever you apply an Exchange Server service pack update to the server
where you have made these changes, you must re-apply all of the changes as
described in this document after the update.
