I am installing a VM only standalone Unity ,version 4.5, the Operation system comes with the Platform config is windows2003,the exchange is exchange 2000. when I install exchange2000, it gives me the error message, this version of exchange can't be supported by operation system. and after the install, the exchange didnt come up , and after I install exchange SP3, it comes up,but I can't put any patches and upgrade on. and we checked somethig on Microsoft website , iAll of the Microsoft references say that we should not even be running Exchange 2000 on Windows 2003. please advice, thanks
