I encountered an issue with SEP 11 in a test environment and was shocked to find out that I was not alone:
Clearly Symantec could not have tested SEP 11 adequately before releasing the product. It has created such serious issues for so many people that I find it hard to believe it was thoroughly and widely tested.
Symantec has acknowledged a code issue and a fix is being worked on, but in the meantime, DO NOT install this product or it will trash your network.

Rubbish
We have deployed to over 5500 machines. Previous to that we did a pilot, and we never encountered an issue such as "will trash your network". I have been in touch with Symantec, and while they state there are issues (minor) and a maint. pack is due in December, they have received NO reports of the product TRASHING customers networks. I find this difficult to believe, especially considering the poster did not provide ANY details.
I disagree with the above.
I disagree with the above. It's great that it worked in your environment, but in mine, it blew up certain network functions completely and also drops a faulting application error on each and every PC in my domain. My PC's won't pickup DHCP even with the smart application for DHCP enabled in SEP11. I also completely dislike that you have to install the manager that uses IIS. I've also had several port conflicts with other applications and SEP manager. They should have taken the SNS environment into conisderation when they developed EP.
My 2 cents for all you whiners...
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.

I have problem with my wireless network after installing SEP and the above explains it. Though there is no fix for it yet.
Obviously a Symantec
Obviously a Symantec shill.
"Symantec 11? Yeah, great stuff!! No problems here! You guys must not have tested properly!! I rolled it out to 5500 clients with no problems!!"
How much are they paying you?
It is almost universally accepted at this point in the IT industry that SEP is garbage. In fact, this product is so bad that Symantec has recently backtracked on their original licensing model after all the negative feedback received. They are now offering extended 10.x licensing to help mitigate the flocks of clients that they are losing to competing products.
In conclusion:
Sorry buddy, I don't buy it.
Maintenance pack?
I'm tired of upgrading.
I'm going to at least evaluate two other vendors (thinking Sophos, McAfee and SEP11) but if I stay with Symantec and push it out to my network... will the maintenance revision be automatic or will I have to push to all my machines (>3,000) again ?
Thanks

It lists the steps involved in upgrading to Symantec versus switching vendors to Sophos.
i agree
many functions in SEP 11 not working.
Exclude hosts from IPS... excluded hosts still blocked by IPS.. :-(
etc..
sig.dat stored on disk unencrypted. If copy this file over network, SEP detected intrusion and blocked communication....
SEP = Sh.t End
(sorry for bad english)
worst software experience ever
All I wanted to do was update the license for Symantec Enterprise AV. But, Symantect told me to update to SEP 11. They told me it was smaller, faster, better, simple to install, no problems at all. So, I installed it on SBS 2003. The 35 MB install that they told me about turned out to be 1,250 MB and used all available RAM, and it still didn't have enough resources to properly run. I have a 2 dual Core Xeon with 4 GB RAM. Symantec support told me to uninstall the server part and only install the unmanaged client. I did that. First thing that happened is all network resources were blocked by the firewall. Users could not get to anything they needed. This was easy enough to turn off, but it should not install like this on a server. After installing, the server would lock up every few hours and the only thing that would get it working again was a hard reboot. After a couple days of this, and many hours of user frustration, I uninstalled SEP. But, the uninstall hung the server and required yet another reboot. All these hard reboots are not good. It seems to have corrupted my Exchange database. Now I am fixing that.
Conclusion: SEP sucks. It has caused abouth 35 hours of downtime on a server that had about 2 hours of downtime in the last 2 years. I will probably lose this client over this.
No problems yet
Installed SEP 11.01000 MR1 and patched with latest update 11.01006 on Test Server Win 2k3 SP2 and pushed to a few test workstations XP Pro SP2. Have not encountered any problems for 2 weeks. Waiting to do live deploy after March 21st MR2 patch release...which is suppossed to correct instability problems many other people have been having problems with.
Sorry to hear about problems others have experienced but standard rule of thumb for any experienced IT administrator is to never go live with new software until at least 6 months after its release. I can't even imagine deploying something relatively untested on an Exchange server...I'm not sure I can agree with the conclusion that SEP sucks based on these facts at this time.
