Hi Experts In my company, there is a Windows 2000 Data Center Edition with SP3 They want to upgrade to Windows 2003, (please, don´t ask why up to now), I thought that installing SP4 for Windows 2000 will allow me make the upgrade, but SP4 its just for Server and Advanced Server, it´s that right? Any ideas? According with this note http://support.microsoft.com/kb/260910/en-us Windows 2000 service packs are for Windows 2000 Professional, for Windows 2000 Server, and for Windows 2000 Advanced Server.Jefe Sioux
