software restriction policy error

[Terry]

I have an asp.net application that is creating a report, converting the
report to a pdf, and streaming the pdf to the browser, IE 6. The app has
been running for a couple years with no problems. Recently a couple
workstations have started to have a few problems. Most of the workstations
running this app, whether they are having a problem or not, are running XP
Pro.

The app starts to stream the pdf to the browser, the browser opens the
acrobat plugin (I can see it open in Task Manager), but the acrobat
interface does not appear in the browser and the browser is now locked, you
can't click on any button, tab, or menu.

The only option at this point is to go into Task Manager and kill the
IExplorer.exe process and the AcroRd32.exe process. Now the odd thing is
that after doing this you can go back into the application and everything is
okay. The application will run without problems until the machine is
rebooted.

I looked in the event viewer for the computer and found that a system error
is generated when this happens. The message is "Unable to start DCOM server
{0002DF01-0000-0000-C000-00000000000046}. The Error:
"Windows cannot open this program because it has been prevented by a
software restriction policy. For more information, open Event Viewer or
contact your system administrator"
Happened while starting this command: "C:\Program Files\Internet
Explorer\iexplore.exe" -Embedding

I'm not sure what to look at to resolve this. Could there be something in a
software restriction policy that stops acrobat from running just once? Does
anyone have any ideas?

Thanks
Terry

I don't have a direct answer but I would take a look at the XP Pro computers
that do not have those problem and compare their configuration to the XP Pro
computers that do. You can run rsop.msc on each computer to see how each one
has Software Restriction Policy configured to see if there is a
fference. --- Steve
