Sorry, I focused on one aspect of your post and failed to consider the larger
picture. Let's see if I can remedy that.

Am I right in assuming, from the way you couch this, that your program and its
functions do not involve a Win 2000 generation server in any way? If that is the
case, then I doubt redistributing dsclient.exe is a legal usage. Are the two
DLLs in your Subject line the only ones involved? If so, which versions? Only
the ones available in dsclient.exe?

Suggest you see
http://support.microsoft.com/servicedesks/fileversion/dllinfo.asp and research
the versions available for each, and their distribution. Note that schannel.dll
has an Export version, which I take to mean that certain versions are probably
*not* for export outside the US.

>From what I infer from the article, the expected method of distribution for
dsclient.exe is for the server administrator to make dsclient.exe available for
network installation, download to the client, or even pushed.

If the functionality of the program involves Win2K-based server(s) and all you
wish to do is make the client available in a more convenient manner, then I see
no problem in redistributing the EXE--which you would get from a WinServer CD.

However, in all other cases, I suspect that MDAC updates, VBRUN service packs,
or any number of other redistributables would be the more kosher method, and
probably more appropriate, considering the "packaged" nature of these runtime
libraries. If you can provide me with the DLL names and versions required, I can
fairly easily see which packages and which versions would satisfy your needs (I
have most of them on my HD, and the rest of them somewhere in this mess.)

At least, that's the way I see it. I can't comment on alternative code. Not my
thing.
