Are all of the COM components you are using in your app registered on the web server? Did you
distribute the COM interop assemblies (if any) that were created during development (should be in
your bin folder)?

Hi Paul,

I think so. On my development client I referenced "domobj.tlb " which is
part of the Lotus Notes Program Directory. When I compile it I get a
"Înterop.Domino .dll" in my bin-directory. I then copy everything in
app-folder, including the bin-subdirectory, to the external IIS. On
external IIS, Notes is installed so I guess the COM component is
registered correct. Is there a way to check this?

Thanks!

Re: IIS - Cannot create ActiveX component

You need to register the COM libraries on the server. The Notes installer
doesn't correctly do this.
The one you're looking for is nlsxbe.dll in the Notes install folder on the
server.

Re: IIS - Cannot create ActiveX component

Hi Ian,

yes, I already did that before (sorry I forgot to mention. I read it on
an internet page but as this was not successfull I wasn't aware that
this might be a needful information). I called "regsvr32 nlsxbe.dll" and
it says "DllRegisterSer ver in nlsxbe.dll succeeded, nevertheless the
ActiveX Object could still not be created.

Did you un register the component before re-registering?

regsvr32 -u nlsxbe.dll

Re: IIS - Cannot create ActiveX component

Does the account the IIS worker process is running under have access to the
Notes folder on the server ?

Re: IIS - Cannot create ActiveX component

Hi Paul,

no, I did not do this before, but did it now. It says
"DllUnregisterS erver in nlsxbe.dll succeeded". Then I registered it
again with "regsvr32 nlsxbe.dll" and it says "DllRegisterSer ver in
nlsxbe.dll succeeded.". Nevertheless, when I start my Webservice it
still says "Cannot create ActiveX component" :-(

By the way, I also tried what happens if I just unregister and then
start the webservice and it's the same error message "Cannot create
ActiveX component". Does this help? Many thanks for your patience!

Did you verify that the CLSID LocalServer32 (or InprocServer32) entry in the Registry points to the
correct location of nlsxbe.dll?

Hi Paul,

yes, it's set to the correct filepath.

Do you know whether this component requires any supporting files? I'm beginning to think that
another component is missing or not registered.

The Dependency Walker utility (http://www.dependencywalker.com/) may help identify supporting files.

Re: IIS - Cannot create ActiveX component

Hi Paul,

many thanks for your patience, but this is now far beyond my
knowledge... I'll contact an external developer to come here and check
it. As soon as it's working I'll post it here.

Nevertheless many thanks for your excellent support!

Re: IIS - Cannot create ActiveX component

I'm having a similar problem, my application can initialize a notes
session and access data OK from within visual studio. When I try to
deploy it to IIS I get the Message "Cannot create ActiveX component"
the first time I try to run the application after IIS is restarted. If
I try again I get the message " Retrieving the COM class factory for
component with CLSID {29131539-2EED-1069-BF5D-00DD011186B7} failed due
to the following error: 8007000e."

The notes client is installed on the IIS server, I have registered
nlsxbe.dll and have copied the dll files from the bin directory on my
development machine to the IIS server.

Have you any ideas what else I could check?

Thanks.

Re: IIS - Cannot create ActiveX component

Hi all,

the external guy now got the webservice running. He played around with
several settings, but the thing he said which most probably fixed the
problem: He gave 'everyone' read-access to the Lotus Notes Directory. I
only tried with the ASP.net-Account and this was not successfull.

Nevertheless I have a strange feeling about that. For me it seems that
some changes are not processed by IIS immediately but you have to wait
some minutes until they are set up.....

However, now it's working and I'm glad. Hope this helps.
