How to do Load Balancing in VB COM?

Component load balancing is supported by Microsoft AppCenter. I seem to
remember reading an MSDN/MSJ article a while ago that described COM
intercepting for implementing a basic load-balancing scheme but I'm afraid I
can't find a reference to it at the moment, but it certainly couldn't be
implemented solely in VB.

An alternative approach might be to look at load balancing the thing
instantiating you VB components. If you are running in a web environment,
then load balance the IIS servers and have each of them run their own set of
VB components.

Another way might be to instantiate your COM components using SOAP and load
balance the multiple IIS servers exposing your components (see the Visual
Studio SOAP toolkit).

You can load balance IIS using WLBS (web load balancing service) which is
part of Windows 2000 Advanced Server.

Hope this helps.

Best regards,

Use MTS and break your system up with MSMQ (if this is appropriate).
You can then use these technologies to load balance.

MTS allows you to run different DLLs on different servers, allowing
some degree of load balancing.  MSMQ has proper load balancing.

I am afraid MS hasn't really come up to speed in load balancing yet
(IIS can do it).  Load balancing of servers in general is also poor.
I understand you can get some clustering third party software.  

The grass may be greener on the other side of the fence, but it still needs cutting.

I found out that there are no such thing.
It's a genereal CLB for all COM.
