DHCP problem

[xor2]

Hey
I am writting dhcp server .. so i have few questions.
First one:
I have seen in real protocol (with sniffer) that
when dhcp server (XP system) sends information, it doesn;t contain dns IP numbers, however in option section there is entered ip address of gate (192.168.0.1). I have been trying to put there real dns numbers (in my onw dhcp server) but client doesn;t even read it.
How to update dns numbers on clients machine sending dhcp protocol??
Sec question. I have seen in RFC that there are 3 timers./
T1 renewing, T2, rebinding and IP lease time.
Which this timers correpond to time values in dhcpd config (there is default and max lease time)??

Really thanks for help

I hope this answers your DNS IP question...
In DHCP - under Server Options, configure 006 DNS Servers (add IP Address) and 015 DNS Domain Name (yourcompany.com).
At the workstation make sure the TCP/IP prperties are set up to 1. Obtain an IP address automatically and 2. Obtain DNS server address automatically.

Need some clarification. XP cannot be a dhcp server, unless I'm wrong. Not a xp pro though, so let us know. What is the os of the server?

I am using XP Professional system, which doesn;t contain real DHCP server program, but it has small version of it, It is included in internet connection when it makes internet available to computers in local network.

First question i have already solved. WIN98 client must have been rebooted to refresh DNS configuration. Like "WhoKilledKenny" said, when i entered DNS(6) and Domain Name (15) everything is good. (However I don;t still know why dhcp server sends 192.168.0.1 as a GATE in DNS (6) field option.

But the sec answer i am not so pretty sure.
As i said, there are 3 timers. Renewing, rebinding and lease time.
In linux config in dhcpd server thera are "fefault lease time" and "max lease time" Which one are which?

Thanks
