Hi - using Delphi 6 with all service packs

Problem Description

LOCAL (XP Pro, SP2, SQL server 2000 personal version, IIS5)
I build a simple "3-tier" server with a TRemoteDataModule, ADO connection,
ADOQuery and DataProvider, compile and register it locally.
I build a simple client with a TWebconnection added to the datamodule and
the URL points to my localhost IIS server (http://localhost/httpsrvr.dll) -
XP Pro, IIS5
In the client, when I click on "Servername" in TWebComponent inspector, the
registered server appears in the drop down list, and on selecting, a GUID is
added.
When I run the client, all seems well, and the "server notification window"
appears, and I get the correct data back from the DB.

REMOTE (SQL 2000 server, Windows 2000 server, IIS 5, not locked down)
I install the same server on our remote Windows 2000 IIS5, SQL 2000 server
and register it and add IUSR_username execute rights. THe folder holding
the httpsrvr.dll is configured as a virtual directory with IUSR execution
rights and "script and executables" permissions.
I open the client in Delphi and point the URL to the remote host httpsrvr
location.
It shows the remote server in the dropdown list, but NO GUID appears when I
select the server.
However, the client application seems to work perfectly with multiple users
EXCEPT - the server process name appears in the Task mamanger process list,
BUT the "server window" does not appear to advise you it is running - so the
server also behaves differently on the remote server.

What have done wrong (does something need configured on the server which
isn't required locally?) , and is the GUID really necessary for
TWEbcomponents (I get the GUID no problem from the remote server if I use
DCOM, but I need to use TWebConnection as this what the client wants).

Any help would be really appreciated. Weve wasted a whole day on this so
far.

TIA
