DHCPLFR

DHCPLFR (DHCP Log File Roller) is a useful program that fills a gap in the management of DHCP log files in a Windows Server environment. Windows Servers only keep DHCP log files for 7 days.

If someone needs to know who had a particular DHCP address a month ago, the information is no longer available. DHCPLFR solves this issue by archiving the log files, either individually or in one combined log file, before they are overwritten.

1) Create a subdirectory for DHCPLFR and save the dhcplfr.exe program in it. 2) Create a scheduled task to execute sometime AFTER midnight (DHCPLFR works on the prior day's log files). The process should run every day. 3) Be sure that scheduled task has either the '/archive' or the '/rename' option set on it. You can set up two scheduled tasks to run both options, but you must run with the '/archive' option first. 4) DHCPLFR requires .NET Framework 1.1 or greater

USAGE: DHCPLFR /rename | /archive

Options: /rename Prefixes the prior day's log file with prior day's date: (YYYYMMDD-)

/archive Appends the prior day's log file to an archive file named: YYYY-DHCP-Archive.LOG
