Specify the maximum size of a UDP request in bytes. If the response is larger than this size, switch to TCP. If you have set the Force DNS to use TCP policy (
dns.forcetcp parameter), the value you set here for the UDP buffer is the initial size of the TCP request buffer; the size will automatically be increased, if necessary, for a specific response.
The default value is 4096; the minimum is 512.
This group policy modifies the
dns.max.udp.packet setting in the agent configuration file.
