URGENT - DHCP & Vista on a LAN

RouterOS General
1

Hi Guys,

I have a MT (latest, 2.9.34) acting as a LAN router. Everything is working fine, however our users using Windows Vista Enterprise, is not getting IP Addresses from DHCP.

The log shows:

08:15:13 dhcp,warning,info,debug DHCP - Office Users offering lease 172.16.0.120 for 00:xx:D1:3A:81:A3 without success 
08:15:52 dhcp,warning,info,debug DHCP - Office Users offering lease 172.16.0.120 for 00:xx:D1:3A:81:A3 without success 
08:16:25 dhcp,warning,info,debug DHCP - Office Users offering lease 172.16.0.120 for 00:xx:D1:3A:81:A3 without success 
08:18:01 dhcp,warning,info,debug DHCP - Office Users offering lease 172.16.0.120 for 00:xx:D1:3A:81:A3 without success

DHCP Config:

/ ip dhcp-server 
add name="DHCP - Office Users" interface="NIC - Office" lease-time=12h address-pool="DHCP - Office Users" \
    src-address=172.16.0.2 add-arp=yes authoritative=yes always-broadcast=yes disabled=no 
/ ip dhcp-server network 
add address=172.16.0.0/24 gateway=172.16.0.1 netmask=24 dns-server=172.16.1.5,172.16.1.7 wins-server=172.16.1.5 \
    ntp-server=172.16.0.1 domain="blah.com" comment=""

Switching the user from DHCP to a static IP Addresses, fixes all issues. So what issue does RouterOS have with Vista, and why is it not allocting IP addreses to Vista machines?

Really urgent, Thanks guys.

I really need to know why the client is not accepting the lease… :frowning:

I use vista here with MT as DHCP without any issue… Can you see anything in VIsta’s eventlog?

I do have the same problem with dhcp and vista. vista doesn’t get ip from dhcp. we have to give the ip’s manually. did anyone find a solution for this?
