<DIV><SPAN class=609090604-28052008><FONT face=Arial size=2>This is an odd one
but I have had the problem demonstrated to me today as I found it hard to
believe.</FONT></SPAN></DIV>

<DIV><SPAN class=609090604-28052008><FONT face=Arial size=2>I'm using BDS 2006,
Delphi personality plus the TMS component set. The application uses a
mathematical model to simulate heat transfer and does millions of calculations
solving differential equations numerically to generate temperatures over time
etc. The results are displayed in a TMS grid and a TeeChart component draws a
graph of them.</FONT></SPAN></DIV>

<DIV><SPAN class=609090604-28052008><FONT face=Arial size=2>The strange thing is
that the calculations & graph come out fine if the user is logged into the
pc as a local user but not if the user is logged into the pc as a domain user.
The numbers calculated are garbage in the second case. So that's the same app,
on the same hardware, only difference being the logged in user. No exceptions
are generated, it runs without apparent error.</FONT></SPAN></DIV>

<DIV><SPAN class=609090604-28052008><FONT face=Arial size=2>When logged into the
network, the user is part of a large company network (Microsoft Active
Directory) that has a strict lockdown policy where most users are severely
restricted in what they can do or see. </FONT></SPAN><SPAN
class=609090604-28052008><FONT face=Arial size=2>When logged in as a local user
he is in the Administrators group whereas logged in as a domain user he won't
be.</FONT></SPAN></DIV>

<DIV><SPAN class=609090604-28052008><FONT face=Arial size=2>This is running
under XP, SP2. It is recent hardware, an HP laptop.</FONT></SPAN></DIV>

<DIV><SPAN class=609090604-28052008><FONT face=Arial size=2>I can't duplicate
the problem on any of my development or test machines. I'm on a different
network but it's still MS active directory and I'm logged in as a network
user.</FONT></SPAN></DIV>

<DIV><SPAN class=609090604-28052008><FONT face=Arial size=2>A further point of
interest is that a tester, in a different organisation, reports the same issue
i.e. it doesn't produce the correct answers as a network user but does on a
standalone pc. In this case the standalone pc is a physically different
machine.</FONT></SPAN></DIV>

<DIV><SPAN class=609090604-28052008><FONT face=Arial size=2>I'm struggling to
come up with any kind of mechanism that could account for this behaviour. Any
ideas?</FONT></SPAN></DIV>
