Technical Information (for support personnel)

Error Type:

Microsoft VBScript runtime (0x800A01A8)

Object required: 'Application(...)'

/exchange/USA/logon.asp, line 12

CAUSE
This problem can occur because of changes in Internet Information Service (IIS) in Windows 2000 Server. Changes need to be made to Collaboration Data Objects (CDO) to render the data correctly.

RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft Exchange Server 5.5. For additional information, please see the following article in the Microsoft Knowledge Base:

"Q191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack" The English version of this fix should have the following file attributes or later:

Component: CDO

STATUS
Microsoft has confirmed this to be a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Exchange Server 5.5 Service Pack 3.

MORE INFORMATION
To install the fix, perform the following steps on the computer on which OWA is installed:

Stop the IIS Administrator service, which stops the following services (if they are running):


 * World Wide Web Publishing service
 * Microsoft Simple Mail Transfer Protocol (SMTP) service
 * Microsoft Network News Transfer Protocol (NNTP) service
 * File Transfer Protocol (FTP) Publishing service

Stop the Exchange Server system attendant service, which stops the following services (if they are running):


 * Exchange Server Event service
 * Exchange Server information store
 * Exchange Server message transfer agent
 * Exchange Server directory

Copy the fix version of the Cdo.dll file to the Winroot\System32 folder to replace the existing copy of the Cdo.dll file in this folder.

Copy the fix version of the Cdohtml.dll file to the Exchsrvr\Bin folder to replace the existing copy of the Cdohtmll.dll file in this folder.

Reregister the Cdo.dll and Cdohtml.dll files by typing the following at a command prompt, or by clicking Start, Run, and then 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 folders 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.

Restart the services that you stopped in steps 1 and 2.

After you perform these steps, you should be able to use the Exchange Server Outlook Web Access component on this server.
