I have Exchange 2003 running on a Win 2000 server machine. I want to consolidate some of my servers, using my current one(Dell Poweredge 2950 3GB Ram). I currently only have 5 mailboxes but will be upgrading to about 30. I was wondering if I could install Apache (+php +ioncube) on this machine without conflicts. Thanks

You can, as long as it runs on other ports, so you may need to change the default port 80 etc. to 1080 or whatever you fancy.

Would it be considered "bad practice" to do so. Which application would you recomend changint the default port exchange or apache (note I will not be using Outlook Web, and if I do I could provide a link with the proper address)

Well, since I usually change the default ports for OWA, just a habit for extra security, I would opt for that one. That leaves Apache pretty standard, but in the end, it does not really matter, it comes down to a personal choice.
