DMP failure on NTP setup

Answered Question

We've tried to configure our DMP 4400G v 5.2 with NTP against a local server via IP-address. When we hit Apply, we get the message "Contacting ...".

We cannot login in from any other computer and it never stops. The only way to get the control back is by restarting the DMP. Meanwhile, the DMP continues to show its videos as normal. We've tried using the NTP-server from our laptops without any problem. The network is isolated from the internet and has no DNS.

/Björn,


The DMS Suite 5.2 requires DNS.  The issue you are most likely experiencing is the

DMP is failing DNS requests.  If you snoop the wire (wireshark) of the DMP, you will

probably see the DMP initiating a Reverse DNS lookup.


Try adding a Freeware DNS Server in your setup to just test.. this should

resolve the issue.

DNS Server Now Necessary



  • 5.2 Requires a present DNS server.
  • DMS 5.2 exchanges certificates between Show and Share and Digital Media Manager.
  • DNS was recommended, but not necessary (Host file could be manually configured with IP)
  • Not possible with 5.2. Certificates require FQDN


Example DNS Servers: Dedicated server “may not” be required.


  • BIND
  • PowerDNS
  • Simple DNS Plus
  • 1
  • 2
  • 3
  • 4
  • 5

We have installed a DNS server which works for all our laptops, but the problem remains unchanged. The server in this case is a Debian Linux server.

Problem solved! We added the setting for Gateway to the same server as the DNS. The gateway should not be needed but adding this setting, saving configuration and restarting DMP before setting NTP works. After setting NTP a restart is needed again
