If you're having trouble installing the Symantec Endpoint 11 client on a machine that was previously running Symantec AntiVirus server components you may have have to clean up the Windows Installer entries.
You may run into problems if you run the Symantec Endpoint 11 Manager on the same machines as VMware server. Luckily there's an easy workaround...
When installing Symantec Endpoint Protection Manager on a server already running PHP you may get the following error when you try to log in: Unable to communicate with the reporting component. This can be caused by conflicting settings in your PHP.INI file. If your existing PHP installation uses a different version than the one supplied by SEP11 then you can remedy this by specifying a version specific PHP.INI in the registry.
The new version of Symantec Multi-Tier (v.11.02) now includes the full Symantec AntiSpam subscription at the server level if you are running Microsoft Exchange. This now saves our clients hundreds of dollars per year as you no longer have to get AntiSpam separately! If you are already subscribed to support for a previous Multi-Tier version you get this upgrade for free.
Symantec Endpoint Protection 11 MR2 was finally released for download as of last weekend. If you've been fighting with SEP11 since it's release as I have, you may want to check it out.
