I will share a short story of why this announcement isn't worth anything to me. Its purely based on my experience and may or may not be indicative of the software as a whole.
I started a new system admin job around 12 months ago now. All of the servers were up and running happily when I started and I had little to no documentation (its always the case).
2 weeks after I start and im still trying to figure out how all the systems have been setup. I'm playing around on the file server trying to work out the file permissions or something equally as boring when I start to receive some calls saying the email isn't working. My email is working fine so I immediately try and work out what on the users machines is causing this. After a few hours it becomes evident that its effecting anyone that logged in to their system after about 9am, but the people already logged in to the before them are still working fine.
I figure its got to be something on the server end and im getting put under the pump to try and fix it, so I try a magic reboot of the exchange server. This makes it worse as now no one can log in at all. After some digging around I work out that somehow the firewall in Symantec Endpoint that has been installed on the exchange server has decided that its under a DDOS attack and is blocking all the exchange traffic thinking its part of that attack. I disable the firewall and all comes good.
Now it stays like this in its disabled state for a few weeks and I forget that it even had an issue as i battle with the network config (trying to work out whats what). Patch day comes around and exchange gets a patch that requires a reboot. System gos down overnight and when i come back in the morning, no email for everyone again. The firewall had turned its self back on after the reboot and gone back to blocking everything again. This time I uninstall it.
A short while after when doing a system audit I remember that the exchange server no longer has a firewall or antivirus on it, so being the good little system admin I attempt to reinstall endpoint. It refuses to reinstall.
I spend more hours digging around for a solution and I try the removal tool, but nothing I can do will get the system to a state when endpoint will reinstall.. So that is the state our exchange server is now it and has been in for a little under 12 months. I cant afford to rebuild the server, or even reboot it that often. Everything is working and I spend all day hoping that the remnants of endpoint don't suddenly decide to hose the system.
Now this would sound like a nice little isolated issue, however in the following 3 months I have had exactly the same thing happen to at least 3 more servers. All problems were solved by removing endpoint and then I could not reinstall it.
We are just starting the process of a server refresh (new hardware and a new version of windows to boot) and im not planing on running any antivirus on any of them, its just not worth the problems.
