Hi, I have the same problem like here : http://www.symantec.com/connect/forums/sepm-has-new-content-clients-not-updating
The client SEP have green dot on the SEPM (v11.0.6200.754), this last could dowmload the last definition, but it could'nt update the client via puschconnection.
The telnet whit port 80 and 443 work.
The client could manually download the definition via http://10.18.4.15:80/content/{C60DC234-65F9-4674-94AE-62158EFCA433}/120314035/full.zip
You could find log from SyslinkMonitor in attachement.
And in exsecars.log I had all the time this log :
03/15 16:47:41 [2924:5248] Open File Error E:\SymantecEndpointProtection\Serverdata\outbox\agent\352259DE0A12040F00F79A7E79712215\index.xml

But this file don't exist.
If anybody have an idea, thank you.
