part one of this two-part article, SearchWin2000.com's resident Exchange expert Scott Schnoll addresses more reader questions about the often confusing OWA setup process.
SearchWin2000.com: How can I get my Windows 2000 IIS 5.0 intranet server to see my Exchange 5.5 box using OWA?

Schnoll: You'll need to insert the Exchange 5.5 CD into the Web server's CD drive and then install Exchange with Outlook Web Access. Then, you'll want to apply the same level of Exchange service pack that you have on your Exchange 5.5 mailbox server. Also, I recommend a review of the following articles before proceeding:

  • Planning and Deploying Outlook Web Access
  • Upgrading MS Exchange Server 5.5 to the Windows 2000 Platform
  • Installing Exchange Server 5.5 on Windows 2000 Server Quick Start Guide
  • SearchWin2000.com: I installed OWA on a separate machine than my Exchange server. I set my IIS virtual directory, called Exchange, to d:exchsrvrwebdatausa Document = default.htm. When I point my browser to http://mywebserver/exchange, I get the following error:

    Microsoft VBScript runtime error "800a01a8"
    Object required: "Application(...)"
    /exchange/logon.asp, line 12

    Schnoll: There are two known and documented problems that can result in this same exact error message. See KB articles Q279834 and Q248718 for details on both issues, including step-by-step instructions for resolving the problem.

    SearchWin2000.com: I'm trying to install Outlook Web Access on Exchange 5.5 SP4 Standard Edition. The server is Small Business Server 4.5 SP6 and IIS 4.0. I'm getting the '0xc0020002' error. I've reinstalled Exchange, deleted the registry key "HKEY_LOCAL_MACHINESoftwareMicrosoftExchangeSetupWeb Connector" and reinstalled SP4. But I still get the '0xc0020002' error.

    Schnoll: Have you by chance removed cmd.exe from the %systemroot%system32 folder? If you have, this may be the reason for your problem. See KB article Q323730 for details on this issue.

    SearchWin2000.com: I'm running an NT4 SP6 server with Exchange 5.5 SP4. Outlook Web Access was not initially installed. I'm trying to add OWA now. When I run setup and select OWA, the system sits for a while and returns: "Failed while attempting to remove Outlook Web Access." This first occured under Exchange 5.5 SP3, so I tried installing SP4, but no change. Any ideas about what's going on?

    Schnoll: Are you by chance getting error 0xc0020002? If so, this means "System cannot find the file specified." I would first run Setup and then choose Reinstall. This will get the missing file(s) onto the drive. Then, re-run setup again and add OWA. Then, reapply SP4 for Exchange. If that doesn't work, try this:

    1. Start Registry Editor (Regedt32.exe).
    2. Locate and click the following key in the registry: HKEY_LOCAL_MACHINESoftwareMicrosoftExchangeSetupWeb Connector
    3. On the Edit menu, click Delete.
    4. Quit Registry Editor.
    5. Run setup and add OWA.

    SearchWin2000.com: I have Windows NT 4.0 SP6a, a PDC running IIS with all updates installed, and a BDC running Exchange 5.5 SP2. (I am waiting to receive SP4.) Our clients are NT4, Windows 2000 Professional and Windows 98 running Outlook 98/2000. When I try to install OWA with Exchange 5.5, I receive a message that it cannot find the IIS server. When I try to install OWA on the IIS server, I obtain a message that it cannot find the mail file. Am I missing a step somewhere?

    Schnoll: You can install Outlook Web Access (OWA) files during the initial Exchange setup, or afterwards. Exchange can be installed on the same server as IIS, or it can be installed on a different server that can be accessed by the server where OWA is installed. When installing OWA and Exchange on the same server, the World Wide Web Publishing service must be installed and running.

    It sounds like you are trying to install OWA on your Exchange server, and you have not yet installed IIS or Active Server Pages. You might be receiving the error documented in Microsoft Knowledge Base article Q173509

    Since you do have IIS installed on your other server, you could install Exchange and OWA on that server and your users can access the server from there. If you end up installing OWA on your existing Exchange server, don't forget to reapply the Exchange service pack afterwards.

    For more information on installing and using OWA, check out the Exchange 5.5 product documentation.
