When you try to use the Microsoft Outlook Web Access (OWA) Logon.asp file on a BackOffice Small Business Server-based computer, you may receive the following error message:
"Microsoft VBScript runtime error '800a01a8' Object required: 'Application(...)' /exchange/USA/logon.asp, line 12"
This issue can be caused by the Microsoft Exchange virtual directory in Microsoft Internet Information Services (IIS) not being set to run as a program (this is designated by the blue box icon in IIS Manager).

Microsoft Transaction ServerIf the permissions on the Transaction Server Packages are not set correctly, you may be prompted to reset them during the preceding steps. When you are prompted to do so, allow the permissions to be reset to the system defaults. After the permissions are reset, restart the server.
After you restart the server, repeat the preceding steps. If at this point the virtual directory can be set to a program, use Exchange Setup to uninstall and then reinstall OWA.
This problem may be indicative of an unsuccessful Microsoft Windows NT Option Pack (NTOP) installation. To verify your NTOP installation, review the following information:
