Wow..all those problems. Incredible. I have a mix of XP, Vista, 2003 Server SP1 and SP2 32bit and 64bit clients and no issues. I'm using the AV, Firewall and IPS (we even deployed two custom IDS sigs). Everything is working quite well...only issue so far is we get the odd "Waiting for updates" for Proactive Threat Protection. What is SNS? Do you mean SBS? My enterprise does not use Small Business Edition. What port conflicts did you have? Did you bother testing this in the lab first? Seems like you have so many issues, and they could have been minimized by doing some testing first. Incidentally, I tested the product for Symantec. Did you sign-up? You hit the nail on the head when you said i works in your environment but not MINE. That's a big problem for many software companies today - they can't get enough testers. There's only so much you can do in the lab to test a product. You cannot possible account for every envrionment. Buy yourself a copy of VMWare, and replicate a few servers and machines in a vm environment first. You can use Backup Exec System Recovery to do a physical to virtual clone. That's what we did with several real clients and servers.
