SYMPTOMS

If you have installed the Microsoft Outlook Web Access (OWA) component for Microsoft Exchange Server version 5.5 on a Windows 2000 server, you may encounter the following error message when trying to access the Logon page:

HTTP 500.100 - Internal Server Error - ASP error

Technical Information (for support personnel)

Error Type:
Microsoft VBScript runtime (0x800A01A8)
Object required: 'Application(...)'

CAUSE

Changes need to be made to Collaboration Data Object (CDO) to render the data correctly because of changes in Internet Information Server (IIS) in Windows 2000.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server 5.5.


MORE INFORMATION

To install the fix, perform the following steps on the computer where Microsoft Outlook Web Access is installed:

  1. Stop the IIS Admin service, which will stop the following services (if they are running):


    2. World Wide Web Publishing Service
    Microsoft SMTP Service
    Microsoft NNTP Service
    FTP Publishing Service
  2. Stop the Microsoft Exchange Server System Attendant service, which will stop the following services (if they are running):



    3. Microsoft Exchange Event Service
    Microsoft Exchange Information Store
    Microsoft Exchange Message Transfer Agent
    Microsoft Exchange Directory
  3. Copy the hotfix version of Cdo.dll to Winroot\System32, which will replace the existing copy of Cdo.dll in this directory.


  4. Copy the hotfix version of Cdohtml.dll to Exchsrvr\Bin, which will replace the existing copy of Cdohtmll.dll in this directory.


  5. Reregister Cdo.dll and Cdohtml.dll by typing the following syntax at a command prompt, or by clicking Start, Run, and typing the following commands in the text box:
    regsvr32 c:\winnt\system32\cdo.dll

    -and-

    regsvr32 c:\exchsrvr\bin\cdohtml.dll
    NOTE: The paths for the Cdo.dll and Cdohtml.dll files assume that these directories are on drive C; if this is not the correct drive for your system, change the drive letter of the path to point to the correct drive location of the files.


  6. Restart the services stopped in steps 1 and 2 above.


Now you should be able to use the Microsoft Exchange Server Outlook Web Access component on this server.
