Hi,
I have couple of DHCP servers on Windows Server 2019 OS.
By default log files are copying under C:\Windows\System32\DHCP and with 10MB file after enabling the auditing.
Now I have changed the log file size to 100MB but the log file stops logging after 14.2MB. Please suggest.

    Welcome to our new Microsoft Q&A Platform.
    Hi,
    According to this article： Event ID 1030 — DHCP Audit Logging
    It states: A maximum size restriction (in megabytes) for the total amount of disk space available for all audit log files created and stored by the DHCP service.
    So we have reason to think that “-MaxMBFileSize” refers to the maximum size of all audit logs added together rather than the size of a single log file.
    To solve this problem, you can continue to increase the value of the log file size.
    For more details, you can refer this article: DHCP stops serving IPs when audit log is full

    Hope this can help you, if you have anything unclear, please let me know.
    Have a nice day!
