VB Forum / COM / February 2005

Hi there,

we are running a com dll created with vb6 together with a iis 5 and ASP on a
win2k server. This system is productive and works fine at the moment. But
now we want to migrate the intranet server to a win2003 server with iis 6.

After installing my dll and the PDFlib dll (referenced within my dll)  i get
the asp error '80020009' / Permission denied in Line XXX (where line XXX
stands for the line where the object is created -> set obj =
server.createobject("myobj.LBO")) on some sites. But the real strange thing
about this issue is that some sites using this dll work fine and others
cause errors. But after an error is thrown by one of the errornous aspfiles
even the ones that worked before throw errors.

I have looked through google groups and found out that i have to grant
filesystem permissions to iwam_<machinename> and iuser_<machinename>. I have
tried this, I even granted full control to everyone in the folders where the
both dlls are located. But i keep on getting the error as described above!
Are there any other folders where i need to grant access?

The dll runs in an iis6 applicationpool. Are there any settings I have to
change?

I even installed vb6 to this machine to test the dll, which works fine and
to recompile it with works, too

To test all the other referenced Objects within the dll I wrote a small test
file that instances all used "thirdparty" objects and calls some functions.
Even this works fine. Besides the PDFLib i am using
scripting.filesystemobject, scriptingContext, CDONTS and ADO. The funny
thing about this is that we have another custom dll running on both servers,
which is referencing the same objects except PDFLib and it works without any
problems. It did not need any customization of the filesystem userrights!
But PDFLIB is running properly from vb6 and from the testfile.

I hope somebody can help me.

Thanks a lot in advance,
