Is your installation fully patched, and have you pushed those patches out to the remote servers (if any)?
Any specific errors being experienced in either the job, your Alerts tab, or in Event Viewer?
yes media server is fully patched and i removed bexec agent and installed it again after patching media server...
the job only says a "communications error has occured" when the agent crashes. i have memdumps and a debug log of the agent, and i see on the exchange server the .NET Runtime Error when the agent dies...
i opened a support case for this in the meantime.... i hope symantec support can help :( but i dont know how fast they are....
on the exchange server where the crashing agent runs, there were a full bexec installation (eval) which i removed like Symantec says on their best practice whitepaper (regkeys removal hkeylocalmachin\software\symantec and currentuser\software\symantec)
Mmm...have you considered uninstalling the agent, and then pushing it out again? Maybe look into removing the license for Exchange (I have seen this resolve 2 issues I had on my side when backing up Exchange...although restoring wasn't affected.).
i uninstalled agent and pushed again today and a few days ago (after all updates), i will try to remove license on media server but i think its an agent issue, wondering about the Runtime Error of dotNet (yes its installed as a feature on win2008 r2 exchange)
