    just to update you guys on this issue, since we still unable to really pin point what causes the issue.

    last night i did some changes on the OpenVPN configuration to best fit my requirements and to mitigate the situation.

    (1) i changed the topology from net30 to subnet.

    (2) i did shringked down my subnet from /22 to /24 this will cater the clients on the single subnet, /24 is sufficient enough for my current OpenVPN clients.

    As of this writing everything works pretty well no more DNS related issue reported from my helpdesk.

    Again, thanks guys for your individual inputs I greatly appreciate it.

      That's an Oops.
      "net30" needs 4+4 IP's per client. Older (before 2.0.x ?) need this setting. The DHCP pool will take a hit.
      A /24 can handle a mere 30 VPN clients when using "net30".

      The subnet setting, although not default, is the best choice.

      No "help me" PM's please. Use the forum, the community will thank you.
      Edit : and where are the logs ??
