DCOM ErrorHello there,
I have a problem in client - server application. My server is windows 2003. Problem is whenever I try to send collection as an argument to the remote method I get error saying Runtime error 462. The remote server does not exists or is unavailable. It was working till recent days. Not sure whether I changed some security settings. Please help me to get thia resolved. It is taking lot of time. Thanks Harsha On 13/08/2010 11:42, Harsha wrote:

I have put debugging message as first line inside remote method. apparently even that is not logging. So I am clue less what is wrong. Any suggestions will be appreciated.

It is not able to call the method. My first line of debussing message is not getting logged. I doubt it is something to do with security settings inside server. Any ideas? Thanks for replies so far. I have not done this for a while. But you may have to set the end point of
the DCOM from the client to invoke the com remotely. Seems like you are even getting there.

IIRC, you have to install the DCOM on your client using some DCOM utility. That utility let you specify where the server(endpoint) is. Select the rest of the choice to default.

What I thought to have understood so far was, that (from the same client, against the same server-machine) some calls do work - and only a few calls (those with Collection-Params in it) do not (anymore). If that is yet the case, please say so - and please mention also, (for the yet working calls), if these are within the same Public Class - and within the same serverside Binary (the AX-Dll or AX-Exe) which contains the non-working methods. Or is the problem, that "no calls at all" go through? Olaf

My client is Windows XP and server is Windows server 2003. You are right saying in the same public class some method works. But the method with collection as argument of the method is not working. All working and non-working methods are in same class. Hope that gives you clear understanding. Please let me know if you need more inputs.

As most others have already said, any change in the Interface-Defs of your COMponent needs to be followed by making this changed Interface known on *both* sides (any Client and also the Server) - by re-registering.

See also this article: PRB: DCOMCNFG Reports Multiple Copies of DCOM Server http://support.microsoft.com/default.aspx?scid=kb;en-us;180525 Another thing that you can try if you have multiple duplicate entries in the Registry is to delete the ActiveX file, run a registry cleaner(which will find that the file is missing and delete related entries), then register the new copy, and recompile the clients, or any software that use the component.

I have installed it on my client. Even after that issue is not resolved. Now I have converted collection object to Variant array. That is my COM function argument is Variant array rather than a collection object. When Array is empty it has no issue. But if array has some value then I get 'Runtime error 70.

Not exactly that one, but DCOM always madeproblems to me in the past. It was neither really "deployable" (without being "InHouse" at the customers side, playing admin for a time) - and as you experience now, it has its "specialities" (mostly security-related). If these are only a few Classes (with only a few methods in them), maybe you want to check out my DCOM- replacement-stuff - and decide if you want to copy your Classes over and give it a try. http://www.thecommon.net/8.html Olaf On Wed, 18 Aug 2010 21:32:20 -0700 (PDT), Harsha <sriharsha.ga***@gmail.com> wrote:
