I am running Windows 2003 Server with Active Directory and DHCP enabled. the machine: laptop1 receives the IP: 10.2.6.134 from the Windows 2003 DHCP Server. the machine name and IP does not show up when I check the DHCP scope on the server. when I ping laptop1 from the server it resolves the IP: 10.2.6.129 I have used the ipconfig /flushdns and it did not resolve the issue When I run the command ping -a [...]

I’d like to know how could I get the MAC-IP DHCP associations. I know that there is show dhcp leases but it only shows information about the active leases. Asked by mariosangiorgio You are looking for the static mapping. This is part of your configuration, not part of a dynamically generated files. You can get it with : show service dhcp-server You can also see additional informations in ls /var/lib/dhcp3/* Answered by CloudWeavers Check more [...]

I’m trying to get my HP T5740 thin clients to connect to my local network without much success. I asked a question here but haven’t got any response. I think that question should have been posted on serverfault instead. I was thinking that the problem seems to be that the thin clients aren’t able to get an IP address when they are connected and I can’t manually set it. So if I was to somehow [...]

What I have in mind and used is a commercial gateway/firewall with an web-interface for configuration that has this specifications: Administration Network Monitoring and logging Authentication Firewall IPS and iDS VPN server Multiple internet gateways Bandwidth management Public dns Application firewall SSL-VPN webportal High availability Content scanning: web traffic Content scanning: mail traffic Statistics But the software comes only at cost embedded on their devices. What I found as a free alternative on internet is [...]

I’ve been debating with myself about the best place for hosting a LAN’s DHCP services. I have the option of either on a sonicwall firewall or a Windows 2008 server. The two things I was looking for in addition to just handing out IP addresses were assigning a small handful static IPs through DHCP (for printers and other various network devices), and assigning three DNS servers (The server’s DNS IP, and two DNS IP’s from [...]

I’m experimenting with PXE lan-boot on my Mac OS 10.6; After some prolonged trouble shooting, I’ve gotten to the point where LaunchD is nicely running bootpd with the following options: <?xml version=”1.0″ encoding=”UTF-8″?> <!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”> <plist version=”1.0″> <dict> <key>detect_other_dhcp_server</key> <false/> <key>bootp_enabled</key> <false/> <key>dhcp_enabled</key> <true/> <key>old_netboot_enabled</key> <false/> <key>netboot_enabled</key> <false/> <!– <key>relay_enabled</key> <false/> <key>allow</key> <array/> <key>deny</key> <array/> <key>relay_ip_list</key> <array/> –> <key>reply_threshold_seconds</key> <integer>0</integer> <!– <key>use_open_directory</key> <false/> –> <!– <key>NetBoot</key> <dict> <key>shadow_size_meg</key> <integer>0</integer> <key>afp_users_max</key> [...]

In a VMware ESXi 4.1 lab environment*, I have a pair of virtual networks configured (10.0.4.x and 10.0.10.x). On both networks is a DHCP server. The problem is that the networks are routable to each other, and VMs on the 10.0.10.x network sometimes get addresses from the 10.0.4.x dhcpd. Is there a way to fix this behavior and give priority to the dhcpd on the 10.0.10.x network? *I don’t have administrative or networking privileges to [...]

Hi I have 2 NICs on my Windows 2008 R2 Server and I want to be able to have 1 NIC connected to the router (Wan) and 1 connected to a standalone switch (Lan) and act as an DHCP server. I want it to act like its sharing the internet from the Wan to the Lan but be able to manage the ip addresses with DHCP server. Any help appreciated! Asked by 2040techman You want [...]

I know that it is not usual, but could I use dinamic IP address on a server that is running a DHCP Server instead of setting a static IP address on it? Is there a restriction of my Windows DHCP server? Asked by Diogo Rocha If you are asking if a DHCP server can assign itself a dynamic address then the answer is NO. The DHCP server needs to know the IP of the interface [...]

Is a DCHP scope range of x.x.x.100 to x.x.x.200 large enough for 65 dynamic hosts? I manage a small windows domain which has grown some. We now have 65 hosts using a DHCP scope range of 100 ip addresses. Expanding the DHCP scope range is easy as the 10.0.0.0/8 subnet has plenty of expansion room, so I am asking for guidance on how much to expand. What is a minimum size to avoid congestion? What [...]
