Why should I use Microsoft verus ISC (Linux-based) DHCP in an Active Directory environment?
My organization will utilize reserved DHCP assignments almost exclusively for IP connectivity, and as such DHCP must be robust and highly available. For that reason, I am very interested in ISC's DHCP failover feature. However, of prime importance is that our DHCP implementation constitutes no significant loss of features or incompatibility with Active Directory.
1. Will ISC's DHCP implementation work well with Active Directory?
2. Can an ISC DHCP server seamlessly substitute an authorized Windows DHCP server in Active Directory? Can it be established as the exclusive authorized server for Microsoft clients at all?
3. Have you any experience using this failover feature with Windows DHCP clients? If so, does it work well?
4. Lastly, are there any really hard-hitting reasons why, from either an administrative or functional perspective, I might prefer Windows to ISC DHCP with Active Directory?
Thanks in advance, and please be civil. :)

Just wondering if you've noticed any issues using ISC failover.
My apologies, forgot to write up a response.
I've not had any problem, the transition between servers has been invisible to the user end, with only a tiny outage while the servers change.

Thanks Chris. If you don't mind my asking, what OS are you running it on, and with what tool do you manage it?
Solaris, and it's managed on the command line :)

Regarding question three, I meant to ask in terms of user experience using ISC's DHCPd and failover feature with Windows clients, not Windows DHCP.
Incidentally, I looked into the split scope option, and administratively speaking, I agree it's pretty lame by comparison with ISC's failover. If I went with Windows, I would use it in a virtual machine and simply rely on speedy restores from virtual disk backups.
But back to my point: Have you used ISC with Windows clients in an AD environment? Just curious how well it worked and what glitches you may have noticed with ISC's failover (if used).
Much appreciated.
