"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Are you decommissioning the SBS 2003 server?  Did you migrate the internal domain already?

I have seen this before, where you actually need the disks to uninstall it.  I think there is some IIS dependency as well.  YOu may need to uninstall IIS first.  Been a LONG time since I have had to do this.  What's the error from the event viewer?

yes I am decommissioning  the server Everything has been done except moving the fismo and running dcpromo I am running the   uninstaller off the sbs disks I checked the event log no events
Run the exchange uninstaller from add/remove programs.  Pull out IIS first.

Why remove iis first?
Just something I found in notes I have from 3 years ago the last time I did this.
