This command sets the the maximum TTL to 2 days and the maximum negative TTL to 20 minutes.
Parameters
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
The cmdlet immediately returns an object that represents the job and then displays the command prompt.
You can continue to work in the session while the job completes.
To manage the job, use the *-Job cmdlets.
To get the job results, use the Receive-Job cmdlet.
For more information about Windows PowerShell background jobs, see about_Jobs.

-LockingPercent
Specifies a percentage of the original Time to Live (TTL) value that caching can consume.
Cache locking is configured as a percent value.
For example, if the cache locking value is set to 50, the DNS server does not overwrite a cached entry for half of the duration of the TTL.
By default, the cache locking percent value is 100.
This value means that the DNS server will not overwrite cached entries for the entire duration of the TTL.

-MaxNegativeTtl
Specifies how long (1 to 2592000 seconds) an entry that records a negative answer to a query remains stored in the DNS cache. The value must be provided as a TimeSpan.
The default setting is 15 minutes.

-MaxTtl
Specifies how long (0 to 2592000 seconds) a record is saved in cache. The value must be provided as a TimeSpan.
If the TimeSpan is set to 0 seconds, the DNS server does not cache records.
The default setting is one day (86,400 seconds).

-PollutionProtection
Specifies whether DNS filters name service (NS) resource records that are cached.
Valid values are zero, which caches all responses to name queries and is the default value; and one, which caches only the records that belong to the same DNS subtree.
When you set this parameter value to False, cache pollution protection is disabled.
A DNS server caches the Host (A) record and all queried NS resources that are in the DNS server zone.
In this case, DNS can also cache the NS record of an unauthorized DNS server.
This event causes name resolution to fail or to be appropriated for subsequent queries in the specified ___domain.
When you set the value for this parameter to True, the DNS server enables cache pollution protection and ignores the Host (A) record.
The DNS server performs a cache update query to resolve the address of the NS if the NS is outside the zone of the DNS server.
The additional query minimally affects DNS server performance.
Specifies whether a DNS server stores empty authoritative responses in the cache (RFC-2308).
The default value is True.

-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet.
If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer.
The throttle limit applies only to the current cmdlet, not to the session or to the computer.
