Endpoint Protection Small Business Edition

I noticed my clients are not getting definition updates so I checked the server and the latest version is from February 16. I checked the update log and it had been trying to update but failing. It doesn't say why though.
LiveUpdate encountered one or more errors. Return code = 4.  [Server: myserver] OR LiveUpdate Failed.
The server can access the internet OK. I initiated an update manually but it seems to be taking a while... it is just sitting there. Any ideas?

the connection might be getting timed out ; if you are using proxy use this document.

HTTP goes through a filter server but it's open for the system that Symantec is on. I can access the internet no problem from that machine. I looked in the log file but don't really see anything that talks about an error.

I did some testing and the server network communication is fine. Here is what I get when I run liveupdate:

Is Internet Explorer Enhanced Security Configuration  enabled?

If so, then uninstall Internet Explorer Enhanced Security Configuration using Add/Remove Windows Components.

At this point it may be best to open a case with Symantec support. Please update the forum once you have the issue solved.

No, Enhanced security is off. Any other ideas?
