Hello guys. Can you tell me what configuration of servers do you have in your organization? for example: mail server (exchange) file server ISA etc? Thanks

Hi JackMaker,Thank you for posting in windows server forum,you might find tons of information on your question . I would suggest you plan the budget, select the hardware You can take a look at the below link which gives you more understanding of server hardware http://www.windowsservercatalog.com/results.aspx?bCatID=1333&cpID=0&avc=10&OR=12) select the OS you want to use TIPS ===Do not install exchange on DC , so you would need additional server Have a seperate server for ISA Seperate server for DC so for a basic setup , you would require 3 servers ( ISA, DC, exchange)
