We currently have a single Netware 4.11 server hosting both file and print services, a web server for email access, and an email server (GroupWise). We also have an engineering dept all using NT4 workstations in a peer-to-peer setup, all sharing files with each other. We are planning to move to a Win2k network, both on servers and workstations. I’d like some input on which applications I should put on which servers. I’ll most likely purchase 3 new servers, 1 Compaq Proliant 370, 2 Proliant 350’s. The 370 will be our main file/print server. I’d like to put Exchange server and either ISA or Proxy server, and IIS for Outlook Web Access on one of the 350’s, and have that as the gateway with the only routable IP address. The other 350 will a file/print server only accessible by our engineering dept, roughly 1/5 of our employee base. We currently only have 50 users, and expect to expand to 75 users within the next couple of years. Will there be any problems running Exchange Server 2000, IIS, and ISA/Proxy all on one box? With AD, should I have replica’s of the directory on all 3 servers? Any advice would be appreciated.
