[DUG] Com Server registration in Win 2003 SP2

[John Bird]

This may be off the track, but as I have often found that the problem was
not in the area I was looking - is it possible that for instance there is
some security setting is preventing the interface from working?  ie a shrewd
look at what has changed in the Win2003 SP2 might give a hint, epecially to
do with the security model.   If the settings are in the registry it sort of
hints at something like that.

Thanks Rohit for this suggestion. The error I am seeing is for the three Win
2003 SP2 servers I have tried. All fail in the same way. The single Win 2003
SP1 I have tried works OK.
So I am guessing the problem is not related to a problem on one server. 
 
I am learning where to look y reading the manual "OLE/COM - explained"
section for the registry program "RegistryTool". 
 
I've not found a solution yet so any other suggestions are welcome.
 
Russell

It may have nothing to do with it, but it could be damaged dotnet.

Last week I had a situation where suddenly the BDS IDE stopped compiling,
but command line compile still worked.  It turned out be corrupted dotnet2
files.  Reinstalling it did not fix it.  However, uninstalling and
installing again did.  I only found it by comparing every windows exe with
another pc.  :-)

I am (still) working with D6 on a program that provides a COM/OLE services
on windows clients, windows networks. The program allows VB code in MS Word
and other programs to call these com services in my D6 executable. Typically
the services get data from a Firebird DB and pass it to the requestors.
 
The program can register its COM interfaces when it first runs or by running
it with the /regserver command line option.
It registers OK in all MS operating systems win9x, win2000, XP, win 2003,
win 2003 SP1, (but not Win 2003 SP2) and Vista (once we use the "real admin"
logon account). I have verified its registration works on each OS mentioned
in actual sites and in my test setup. I have verified the registration is
only partial in Win 2003 SP2. The com interfaces appear in the registry and
they are removed when I run the program with command line /unregserver.
Using TREGSRV does not help.
 
I repeat that Win 2003 SP1 and below is OK and Win 2003 SP2 gives me this
problem.
 
The dot (myfile.dot) file used when users are running MS Word as part of the
application, when on Win 2003 SP2, is failing to compile.  The VB Editor
tissues the error "Compile error \n Error in Loading DLL" and points to an
object referencing a servive provided by my program. When other programs ask
for com services they are not provided. Yet when I edit this code in the VB
Editor the code completion feature knows about my type library and presents
options from my type library. So my type library seems to have been
registered OK.
 
This appears to be a Win 2003 SP2 bug. But, as the program is a Delphi 6
product I am hoping someone here has some insights for me. We need the
program running on Win 2003 where it is used as a terminal server.
 
Insights will be welcome.
Thanks,
Russell Belding
