symantec backup exec error
i have backup exec 12.5 rev2213 with sp4 installed and all hotfixes i suppose.(liveupdate doesnt show anything new).I have been trying to backup my exchange server for over a week now and am getting an error e800846b, prompting me to ensure ihave the right version of remote agent installed. i have various times reinstalled the agent on all the servers through the media server remote push but still the same issue. the same thing happens while trying to backup my fileserver/sql database.
everythign used to work fine, but started acting weird since over a week now and gives me this error.steps i have tried so far,
performed liveupdate on the media server
removed agent from the remtoe servers, rebooted and reinstalled
open file option is not enabled on the exchange servers
tried registry entry for MonadRpcTimeout on the media server and the exchange server.
installed hotfix 319699
ensured the service account is part of the local admin group (exclusively added)
all services are up and running
the minute the backup starts, the agent on the remote server crashes and backup fails after that.
any help would be highly appreciated and thanks in advnace,
regards
