Set DNS UDP buffer size

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.
