I have installed SBS2003 R2 server, and due to joining to the domain prblems I have decided to remove all SBS2003 install and leave the OS only.
While removing I got the exchange files error remove but in the end it finished/ After removing also the AD and DNS, I have restarted the server and the instal of SBS2003. On the server setup GUI I get the error:
"The computer cannot be upgraded to the OEM versionof windows small bussines server".
What do I do now? Do I need to reinstall OS?

    More info is needed here. SBS is the OS and cannot be a member server.  Sounds like you are trying to use this in the wrong environment.

    What I ment was that after you install the OS of SBS2003, you have additional setup which installs server tools, exchange....
    The last setup, (Exchange, server tools....) I have tied to remove andgot an error in te middle with Active Sync something that is connectedto Exchange remove.
    Now when I try to restart te install if the SBS setup (Exchange, server tools...) I get an error as I wrote.

    Hello toot-solutions,

    the only solution is a complete reinstall of the SBS.
    In an sbs environment you MUST install all components (even if you don't need them).
    Before you start with sbs, please read:

    Also keep in mind after reinstalling that you do not have to join all workstations to the domain. I have plenty of environments where it is a mixed bag of workstations that are joined and in a lot of cases laptops that are not.  It will require user authentication on the disjoined in order to access resources but it works well.  I know it can be a real pain if a laptop has been out of the environment too long and has disjoined.  YOu may want to consider this option when you rebuild and I wholeheartedly agree you need to rebuild.
