Which version of Windows Server do I need?

I am switching hosts and moving to managed hosting. I have ASP3, ASP.NET, MSSQL, PHP, and mySQL that need to be supported. I%26#039;m sure I could make Apache work with Mono or use IIS for XP with ISAPI Rewrite, but this is for a web-based business and I can%26#039;t afford to screw up. I%26#039;m trying to figure out what software to buy, obviously at the best price. Can I get by with Web Server 2003 and SQL Express? Do I need R2 Standard? Small Business Server?





Can someone please shed some insight into what the best OS for an ASP.NET managed server would be?





Thanks

Depending on what you need, 2003 Small Business server might not be a bad choice. That%26#039;s cheaper than buying the OS, SQL Server and Exchange.





Don%26#039;t skimp on the hardware either. If you underpower things, you%26#039;ll set yourself up for disaster.

My suggestion is windows server 2003 web edition. It should support all those features once you%26#039;ve installed the few open source applications that you need like php and MySQL.
