Yes - its called 'Microsoft Small Business Server 2000' (SBS2K) and works very well since its been designed to do so - that is co-exist on ONE machine. OK so you may not need the bundled SQL2000 but it'd probably still work out cheaper than W2K Server + Exchange seperately. IMPORTANT - Only thing is you have to live with a MAXIMUM of 50 CONCURRENT connections(you can have unlimited accounts) as this is hardcoded. Regards Nigel TechBase
