Windows Vista clients cannot obtain IP addresses from DHCP server on RB493. The reason for this is outlined on the Microsoft website as a failure by the DHCP server to set the DHCP BROADCAST flag.
See article http://support.microsoft.com/kb/928233
My question is: Does the RB493 support the DHCP BROADCAST flag? If so, how do I enable it so that Windows Vista Clients can obtain IP addresses?
have u set pool, add entry to adresss list?
Yes I have set the address. What entry and to which address list? The addresses are supposed to be dynamically given and not static
Ect.
The RB493 is set up properly. All the pool, address and IP are set up well. Clients from Windows XP, GNU/Linux get IP leases correctly. It is only Windows Vista and Windows 7 which has this problem. Microsoft is aware of this problem as mentioned in their knowledge base article at http://support.microsoft.com/kb/928233
create static dhcp lease for W-7/W-V based systems.
DHCP is working here with Vista and Win7 clients, the computer I am typing on is Win7 using MikroTik DHCP. Maybe you have another DHCP server on the network?
Here is my config, maybe it helps you.
/ip dhcp-server
add address-pool=private authoritative=after-2sec-delay bootp-support=static
disabled=no interface=“private bridge” lease-time=3d name=“private dhcp”
/ip dhcp-server option
add code=15 name=primary-dns-suffix value=office.local
/ip dhcp-server config
set store-leases-disk=5m
/ip dhcp-server network
add address=10.69.77.0/24 comment=“” dns-server=10.69.77.254 domain=
office.local gateway=10.69.77.254 netmask=24 ntp-server=10.69.77.254
wins-server=10.69.77.130
/ip pool
add name=private ranges=10.69.77.1-10.69.77.99
This is a non mikrotik related problem. This is a Windows problem that seems to have developed after Windows XP sp2 and Vista. Here is a link to Microsoft’s site to correct this problem on the PC that is having the problem. This problem was giving me so many headaches until I stumbled acros the fix on Microsoft’s site. I ran their fix it tool and the dhcp addressed Vista machine that I am posting this message from now works better than ever.
Side noted problem is broadcast related. It would seem to peg the broadcast bit, which than caused streaming and xbox live packets to drag and drop.
Anyways here is the link I hope it helps your customers out as much as it has helped me.

Never tried on a 493, but on 433s and 450s, I have at least a dozen vista/Win7 computers that have no problems getting an IP…
