>Hi. I've created a simple DLL.
>For starters, I registered it on my machine.
>I can intantiate the DLL if I issue:
>X=CREATEOBJECTEX("{5BBFA780-1073-11D8-A062-0050BA3FFB2E}","")
>I get a 'class not registered' error when I issue:
>X=CREATEOBJECTEX("{5BBFA780-1073-11D8-A062-0050BA3FFB2E}","\\maserver") --- even though my computer name in our domain is "maserver".
>
>I've registered this same DLL on nycServer.
>Again, I can instantiate with:
>X=CREATEOBJECTEX("{5BBFA780-1073-11D8-A062-0050BA3FFB2E}","")
>but not with:
>X=CREATEOBJECTEX("{5BBFA780-1073-11D8-A062-0050BA3FFB2E}","nycserver")
>
>The reason that I'm doing all of this is to be able to run:
>X=CREATEOBJECTEX("{5BBFA780-1073-11D8-A062-0050BA3FFB2E}","nycserver")
>FROM maserver.

>Any help would be appreciated.
