Hi All,
     I have a Customer running SBS 2008. I suggested to them that I was going to install BES Express for them. Over the weekend it seems they got impatient and tried to install it themselves. When it didn't work they tried to uninstall it but it didn't uninstall completely.

Now I can't uninstall it even after restart and it won't install either, it gives this message..

"BlackBerry Enterprise Server for Microsoft Exchange -- Internal Error 2803"

and logs this event.

Do a search through the registry and remove all instances of 'blackberry'.  Did they create the besadmin user?

If i do that will I then be able to reinstall BES?

No they didn't create the user, I did before I realized that it was messed up.

You should be fine after you remove any namings of blackberry in the registry.  It won't even know anything is on the box after a reboot.
Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Unfortunately I'm still getting the Internal Error 2803.  While logged in as administrator I have manually removed BES Express.  I then login as besadmin to try and reinstall.  If I run the setup.exe nothing happens.  I then try to run the BlackBerry Enterprise Server.msi and that is when I receive the 2803 error.

Thanks again for the help and I apologize for jumping in like this.

Did you Google manual removal of bes then restart?

Yes.  These are the instructions that I followed: 

At first I thought there was an issue with their msi installer, but I reinstalled that as well.

I did see an event id 1000 with description:  faulting application Setup.exe, version, faulting madule ntdll.dll
