    I found a workaround solution to my problem by activating the error Handling-Rules.

    More specificaly when I enabled the

    Network-Server-Resource errors rules (by having them to retry the operation for 2 more times every 10 min.) all my jobs were completed succesfully even when they failed the first time.

    Possibly the source of the problem had to do with network and/ord DNS issues (in the first place) so until I find the real origin of the problem I applied this technique which is working just fine for the last couple of months.

Hi pkh

1) The service is up and running. Further more there's also a 1st Recovery action set up to the Restart the service.

2)The remote agent is published with Full Domain Name

3)Pinging correctly with DNS and IP and vice-versa

4)The firewall service is disabled.

5)TCP port 10000 is listening only and also checked during the telnet session which correctly listed as in use by the media server.

Telent session performed from the the media to the remote server succesfully but only when I use as host the IP and not the DNS name (I'm not sure if this is a problem)

The question now based on the above findings is related to step 2. Does the remote agent needs to be published with the Full Domain Name, with the IP or both. I;m not saying that this can cause any problems. I'm just asking because I can't see any other obvious reason.

Also, be iinformed that the problem occures with VMs and Physical Servers, The jobs very same servers are running succesfully (with full-Icremental-Full-Incr cycle) for the last 4-5 or more days
