Re: Unknown trust error when downloading ocget.dll
From: Garry_Stewart () veritasdgc com

I've been battling this for a couple of days now too ...

I have one thing to add to what Ken said, and that is ... If you turn on
the Prompt for Unsigned ActiveX Controls, then I've found that you get a
prompt to install and run http://codecs.microsoft.com/objects/ocget.dll
Which clearly is a bug to me ... since it should be installing the activex
control and not the ocget.dll.

My page is simply trying to install the mscomctl.cab from
http://activex.microsoft.com/controls/vb6/mscomctl.cab#version=-1,-1,-1,-1

Another interesting thing I found was Microsoft's KB article Q323207.
Their resolution is to remove the two URL's for the ocget.dll from the
CodeBaseSearchPath in the registry.   I tried that, and decided to add
http://codecs.microsoft.com/objects/ocget.dll to it too, and that worked.
Hardly a viable solution though, as I'd hate to have modifying the registry
as a requirement for using my web page.

Comments?

Thanks,
Garry Stewart.

Greetings,

We have run into a problem this afternoon with the copy of
ocget.dll that is located at:
 http://codecs.microsoft.com/objects/ocget.dll

It seems that it is either signed improperly, or not at all.

This .dll is loaded automatically by IE when .cab files are
downloaded from the server.  Usually it is transparent, if
the signature is ok.  Since that is no longer the case, our
users are getting an access denied message due to the security
settings on their browser.

Since ocget.dll is not really a required download, according to Microsoft
( http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b323207 )
the pages still display correctly.

The users are still blaming our programmers for the problem, of course :)
Not to mention the possible security implications here.

Is anyone else seeing this behavior?

( Verified on: Win2K/IE5.5-SP2, Win2K/IE6.0-SP1 and WinXP/IE6.0 )

Thanks.
