I was able to fix this -- I used the registry fix described below:

Here is how to fix this problem when using TS. I have tested it both on the 32-bit version of Windows Server 2003 and the x64 version. Works (for me):

1. Download the latest Flash uninstaller on this page: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=1 and place it somewhere on your hard disk (C:\Temp is a good place)
2. Open a command prompt, navigate to the folder where you placed the uninstaller and run it with the "/clean" option, like this: "uninstall_flash_player.exe /clean" (without quotes - thanks Adobe for so clearly documenting any command line options for this tool...NOT !)
3. Click the Details button. If it lists any files as "Delete on reboot", then reboot now. Otherwise, just carry on.
4. Download the EXE installation package from here:
http://www.adobe.com/support/flashplayer/ts/documents/tn_19166/Install_Flash_Player_9_ActiveX.zip
5. Use the Control Panel Add/Remove programs method to install it. This ensures that the Windows install notification API triggers correctly (as opposed to executing change user /install in a command prompt).
6. Use regedit and find the following key: HKCR\CLSID\{D27CDB6E-AE6D-11cf-96B8-444553540000} (on 64-bit Windows this one is located under HKCR\Wow6432Node\CLSID\{D27CDB6E-AE6D-11cf-96B8-444553540000})
7. Remove any permissions for the Everyone group. click Advanced and tick the box to propagate the permissions to all child objects.
8. Add the Everyone group and give it "Read" permissions on the key. Again, click the Advanced button and propagate the permissions to all child objects.
9. Repeat steps 6 to 8 on the subsequent key, called HKCR\CLSID\{D27CDB70-AE6D-11cf-96B8-444553540000}

I got this from a similar thread on this forum, but I do not have the link, if someone could provide the link, that would be nice.

Thank you, Tom

Hi Tom,

I tried the proposed solution above, but when I log in to the presentation server as a test user, i get the following prompt:  Adobe Flash Player has stopped a potentiallly unsafe operation.  The following locatal application on your computer or network is trying to communicate with this Internet-enabled location.  To let this application communicate with the internet, click Settings.  You must restart the application after changing your settings.

If i click on settings and select always allow, I still get the same prompt if I log out and log back in.  If i log onto the server with my domain admin account, I don't see this error message.

Please help.

thanks,

Jen
