• Requirement of DNS and DHCP Server Essentials 2012 home

  I have a Server Windows Essentials 2012 acting as DNS and DHCP server with a domain name for backups etc on my home network. It's that everything works fine, no errors, no problem. Works well actually, telling me when the children did not install updates or restarted.

  I have two groups of users. My sons step, 10 and 12, which I want to use OpenDNS as a provider external DNS with a policy very, very limited and my wife and me who want to use indications of root or Google DNS or any other DNS provider. Others, specific devices no user (box of the xBox, WII, Satellite, TV, CCTV etc.) can use.

  Before the 2012 server, I had a 2 k 3 server running in a virtual machine for DHCP, alone and put my wife and my devices on static reservations with the just and external DNS provider used OpenDNS as the default scope, DNS. Unfortunately different bits of domain services 2012 don't seem to work unless the server of 2012 is the first DNS server listed on client machines (backups failed. Impossible to find other local computers). Currently, this means that we are all using OpenDNS.

  What I would like is a way to say 2012 to send adult group DNS queries to another DNS provider and leave the rest at default to OpenDNS, while still having them register in the original DNS domain. Any suggestions?

• Using Cisco AP as router and DHCP server

  I'm a newbie in the technology of Cisco wireless. I have a lot of Cisco wireless access point. One of them (1142AG-K9 Cisco) I want to set them up as a DHCP server and will forward traffic to the public ip address as it will route the traffic to 203.82.203.50 (Ip provided by ISP) and will lease ip as associated devices 192.168.10.0 pool.

  Even though I know that it is possible using a router on the AP. But it is possible using a single access point?

  If so, how?

  Help, please.

  Hi, the AP cisco are just basic layer 2 devices such as a hub or Layer 2 switch, it does not any layer 3 as a wireless router.

  The Cisco access point supports to have a VLAN or subnet configured or more VLANS or subnets and will pass all traffic to a layer 3 devic so that traffic can be routed to the need.

  The Ap can't stand to have an addrees ip configured on the bvi1 for the management.

  Also the build in the ap dhcp option is very limited and will only know the ip address to wirless clints that connect to it on an ssid linked to its management interface in this case that the bvi1 and all them VLAN othe or subnets shall not use an external dhcp server.

• Series of unmanaged switches 100 and DHCP

  Hi all, we have a router RV082 switch 8 ethernet ports, it is actually 8 lan with a DHCP address assignment devices (router is used as switch/router and DHCP server).

  Now we need to increase the number of attached LAN devices (other pc, printers, etc.), and we think buy Cisco 100 ethernet switch Series 16 or 24 ports to connect to RV082.

  In this case RV082 will be able to assign DHCP addresses for devices connected to the eth switch ports?

  Thanks in advance.

  Hi Loris, yes it is not a problem. You should be able to switch on a lan port, connect computers to the switch and things should be OK.

• RV320 as SBS2011 router as DHCP server and use IPSEC

  p {margin-bottom: 0.25 cm; line-height: 120% ;}}

  Our society is really eager to acquire a VPN Cisco RV320 router to replace our old insecurity only PPTP VPN-router. Before actually buying the router, there are a few questions I'd like to have answered.

  In our current setup, we have a SBS2011 standard Server which is used as a DHCP, DNS, Exchange, and SMB server to our network of the company, all the peripheral functions within the same network (192.168.0.1/24).
  We would like to add the RV320 to our network to allow access of employees to the corporate network when they are at home or on the road using IPSEC VPN (client site).

  In our current configuration us use (or used) a VPN router and VPN clients allowed to acquire an IP address from the PPTP server, these IP addresses have fallen in a range that the DHCP SBS2011 server was free to distribute the. It's quite simple actually

  How can we configure the router RV320 so that there will be any conflict between the RV320 router and SBS2011 Server regarding distributing them IP addresses to the VPN IPSEC clients?

  Can configure us the RV320 to transfer earlier requests DHCP server SBS2011?  We want all customers (including IPSEC VPN clients so that they enter the same network).
  Is it possible to simply using the DHCP-relay option (in the web interface) and entering the IP address of the server SBS2011?

  We should disable the DHCP on the router-RV320, or is there another way to continue using the SBS2011 server as the DHCP server, while allowing client-to-site IPSEC VPN for access to our local network?

  Thanks in advance

  Hello and thanks for the exam Cisco for your network needs.

  First of all, I understand that you are used to working with the PPTP connection and now you want to switch to a more secure IPSec connection.

  It's a great idea, but there are a few things to consider:

  1. the RV320 supports the IPSec VPN via the Cisco VPN Client 5.0, you can download it from the site Web of Cisco if after you buy a contract for the router.

  The contract will set will cost about $70, depending on where you decide to buy it, but it has several features including 3 years of telephone support 24/7 and next day replacement guarantee for business if the unit doesn't respond, it also allows you to download special software like the Cisco VPN Client.

  2. for client VPN connection, you can not, or you need to try to relay the DHCP request what, whether the router will handle it and he will probably be on a different subnet from your local network, but it will you access to all devices on the network.

  3-If you do not want to buy the contract, then you can always use PPTP to the RV320 and it will give you the same access that you are already accustomed.

  I hope that was helpful, please let us know if you have any other questions.

• hostname gets vmnet8 form ip and no default dhcp server

  Hello
  
  I installed VMware Workstation 7.1 last week and noticed that my hostname in my linux box gets the number of ip not default dhcp server but vmnet8 as before.   Is there any way to go back to that?  It has destroyed my samba server.
  
  Thank you very much
  
  Ed

  Comments of vmware can obtain ip addresses from the dhcp linux without vmnet1 and vmnet8 Server?

  Yes, if the virtual machine network adapter is set to Bridged so it will be on the local physical network the host is and should be able to use its DHCP server.

• Satellite Pro C650 can't find our DHCP server

  Hello

  We just recived 8 new Satellite Pro C650 and care about their image.
  When connect us to our network via a cable and boot on LAN of the laptop can not find our DHCP server and so of does not obtain an IP address.

  If we connect to an another laptop\workstation in the same Manor, it works very well.

  All the settings are correct in the BIOS.

  Any ideas.

  Hello

  First of all, you should check if the settings of TCP/IP to connect to the local network.
  Network-> properties-> LAN (local area) connections-> TCP/IP-> properties

  Here, you should check if the options for the IP address, DNS are set to obtain automatically.
  In the advanced settings of TCP/IP in IP settings tab active DHCP must be visible.

  In addition, please check if all firewalls do not prevent the laptop to connect to the local network.

• Keep the IP if the DHCP server is offline now

  We have a customer who wants to be able to manage the IP addresses of all devices with DHCP, but the devices are supposed to keep their IP forever after the DHCP server has been taken offline. Is this a behavior that we can support on a controller of NOR?

  If this is not a configurable behavior an alternative could be to have controlelr auto configure to the last known IP if no such is acquired... but the VI apply network settings doesn't seem to work if done on the controller itself. Is this correct?

  With NEITHER in Norway (thanks), I found a solution which allows us to implement the required behavior.

  The main problem for us once we need to override the default behavior for DHCP was the fact that the RT apply target Network Settings.vi does not work if it is set to target the same controller as it is running. So how to exchange between DHCP and fixed? Well, it turns out that the network settings are also stored in the file of ni - rt.ini. So here's what we do: when the controller starts, we check if it is running in DHCP mode. If this isn't the case, we change this in the file nor - rt.ini and the reset - to see if the DHCP server is operational. If the controller is running in DHCP, we check if the IP address is valid (i.e. outside the local range of link). If it isn't read us the last known IP address and write those set in the file nor - rt.ini and restart.

  An example of the sections of the INI file:

  For DHCP, the section of the nor - rt.ini will look like this:

  [TCP_Stack_Config]

  USE_DHCP = DNS_Address

  Gateway USE_DHCP =

  USE_DHCP = Ip_address

  USE_DHCP = Masque_sous

  For a static IP address:

  [TCP_Stack_Config]

  DNS_Address = 0.0.0.0

  Gateway = 10.0.18.1

  Ip_address = 10.0.18.13

  Masque_sous = 255.255.255.128

  It would be nicer than the network RT target apply Settings.vi would work for auto-reconfiguration, but it saved the day for us at least in this case.

• DHCP Server R2 2012 problem

  Hello world.

  I am new to Windows Server. I'm setting up a server to connect thin clients and use it only as an internet point.

  Server roles installed: SC AD, AD DS, AD FS and AD LDS, AD RMS, App Server, DHCP, DNS, file storage Services, Hyper-V, IIS, IPAM, NAP, remote access, Remote Desktop Services. GOING to Services, WDS, Windows Server Essentials experience, WSUS Server Local, all servers.

  My problem is that DHCP does not dynamically IP addresses in the clients. In trying to check the DHCP problem, I used followed enough of ipconfig ipconfig / renew and got the error message "an error has occurred during the renewal of the vEthernet of the virtual interface (my static IP port): unable to contact your DHCP server. I even removed then added the DHCP function and no change.

  What I am doing wrong? Help, please!

  Other tips on this deployment will be welcome, because I'm out of my League here and have no money to wait for him.

• DHCP server running Hyper-v comments

  Original title: Hyper-V DHCP

  Hi all

  I'm having a problem with a DHCP server hyper-v guest.

  The DHCP server is seeing demand fall, assignment of an address to the pool, but the client pc never receives the details.

  Hyper-v host is 2012r2, the guest is 2012r2 running on a gen 2 VM.

  On the same hyper-v host is our SBS 2011 VMS (which does not not on the legacy network adapter) run DHCP with no problems.

  I'm obviously SBS DHCP services during the test.

  The 2012r2 and the SBS invited to be on the same vSwitch with the only difference that I see the generation of VM.

  Any ideas?

  Thanks in advance,

  Rob

• New DHCP server not to issue the IPS (2012 R2)

• Cannot DHCP server see

  World in the morning.

  I have a problem that I do not quite understand and I hope that it is an answer out there fairly quickly until I shoot all my hair!

  I'm working on a VIRTUAL network IL4 Secure LAN. I have DHCP enabled and configured on a server that also acts as the domain controller.

  I set up the scopes on the DHCP server with the IP address range that he should look on what subnet etc.

  If I use a static IP address, it connects instantly, but when you use DHCP is takes a while to find something while he gives automatic address 169.254 (PIPA)

  Why the client computer cannot see the DHCP server?

  • Client PC is located on the same domain.
  • DHCP enabled on Server services
  • DHCP enabled on IPv4

  Server is 2008r2 and Client pc Windows XP and Windows 7

  Thoughts?

• Can DHCP server with two scopes - I have reservations in doubles in the two staves?

  Hi all

  Not really a guru of DHCP, so be nice :)

  Currently, we run a DHCP service from one of our domain controllers (win 2008R2). The domain controller is the segment of a network (10.10.120.0/24), the computers making DHCP requests are on a separate network (10.10.103.0/22). We use our ip-helper routers setting to say the devices on the network, how to reach the DHCP server. This has worked well for years.  I should also point out it is company policy for PCs/servers have a static IP, so for the PC, we create reservations for each PC. Servers are assigned static mmanually.

  The question is now we have overflowed into a new building and put in a black 1 GB fiber that connects the two buildings. The network in the new building is using a different network (10.10.104.0/24) address. Implementation of a 2nd scope on the DHCP server for this address range went well and once the ip-to support additional parameter has been done on the router the PCs in the new building could fine DHCP to the domain controller in the main building. Everything is good.

  The question is now, we are moving PC between the two buildings, I was wondering if it is ok to keep the existing reserves for the PC in one scope and have a duplicate for her in the new scope assign the new IP address. Of course, the PC cannot be in two places at once and the DHCP console doesn't; "t seem to complain about the same MAC address used in two staves, but I don't really know whether it is advisable or not. Basically, our operations staff become a little miffed at having to remove a single scope of reservations and recreate them in the 2nd scope when the PC to move between buildings.

  So the questions is safe / advisable to do it or not?

  Kind regards

  Craig
