    Post DHCP traffic is blocked by Symantec in Windows Server 2003

    I am running Windows Server 2003 SP2. I have Symantec End point Protection 11.0. Symantec is blocking DHCP server. I have added a rule to allow DHCP in the firewall settings of Symantec Management Console. I have also enabled smart traffic diltering options, but still it is blocking. If I disable the Symantec End point Protection on DHCP server, then DHCP traffic will be allowed. And DHCP server also acts as my DNS server. How to fix this issue?

    Default

    Change the default firewall policy to include a new rule for DHCP server traffic. Because, if users use the default firewall policy with Symantec Endpoint Protection client on the server and the server is performing DHCP server role and workstations will not receive DHCP lease from the server successfully, since the default policy will block the DHCP server traffic. To fix this issue, follow the below article:
