On a computer that is running Microsoft Windows Server 2003 and Microsoft Internet Information Services (IIS) 6.0, static files that are compressed may become corrupted and may include content from other files on the Web server. If this behavior occurs, the page that is returned to the client is not rendered correctly. An access violation may also occur.
Note This problem can affect Outlook Web Access (OWA) users. The problem may cause various script errors to be returned in the OWA pages, or the problem may cause pages to stop responding (hang) when the pages load.
For example, you may receive OWA errors that are similar, but not limited, to one of the following error messages:
Error: 'g_flsMimeInstalled' is undefined
After you log on to OWA, you may also receive an error message that is similar to the following:
Error: object expected
HTTP Error 405 - The HTTP verb used to access this page is not allowed.
