Re: DHCP Logging (can't find a solution!)



ISA doesn't have "Client Host name" in Web logs (as it does in Firewall
logs)
So, I don't know how to log this, how to do this correctly.

Thanks

I know this question has been asked before but I can't find a solution for
my problem: I need to find which host had a certain IP assigned to it in a
specific date.
Windows 2003's DHCP server mantains only logs for a week (no longer than
that).

The normal DHCP behavor is that Clients will always ask for the same
config they had the last time. So barring unforeseen circumstances it
will still be using the same IP config today.

This will be use to analyze ISA logs (which only logs client ip address,
not host names). For example, given the following data:

ISA will log the host name if done correctly.

"2008-01-01,192.168.0.22,www.someadultsite.com"
Which hostname/computer was assigned to "192.168.0.22" in "01/01/2008"?

The ISA log will include the Username, which is more important than the
host name.
Don't use SecureNAT Clients (which can't authenticate) and you will always
get the Username
Don't use generic "shared" user account and you will always know who the
person was.

Without considering all the above, your findings will never be solid
enough to legally enact disipline upon the user(s) if the user chooses to
sue the company over your disipinary actions.
