• The DHCP server cannot be contacted

  I just had this problem but it resolved a few days ago: http://social.answers.Microsoft.com/forums/en-us/xpnetwork/thread/d16f8409-119E-495a-8afa-dffbd310502c

  Now today, I can not connect to internet. The same solution that worked in the above link does not work now. After going through essentially the same troubleshooting technicques I realize that when I run the command ipconfig / renew command, I get "an error occurred during the renewal of the connection to the Local network interface: unable to contact your DHCP server. Request timed out. »

  I'm lost on where to go on it now...

  I was thinking about upgrading to Windows 7 in any case. Do you think it works?

• E3200 in Bridge Mode = > cannot act as a DHCP server?

  Hi all

  can someone confirm that the DHCP server can not be enabled when you configure the E3200 "fill mode" Please?

  (if it is true, it is really bad).

  DHCP server settings disappeared when I configured the router mode "bridge."

  Or have I missed something...

  Except this problem it seems to work great so far...

  (I received it today)

  my config is:

  -some ISPS 'box' connected to the internet

  -use the E3200 as access point.

  (I tried other modes, such as static IP address, but I think that this is not what I need; AFAIU, I should remove the box ISP and connect directly to the internet with the router, that is something that I can't do)

  Thank you

  Olivier gg

  Yes, that would be the case. with the router is set to BRIDGE MODE, the DHCP server is disabled.

• On SG300 DHCP server configuration error

  Firmware 1.3 introduced a DHCP server.

  It seems that I can add a pool for any subnet except for the 192.168.1.1/24. I've successfully added a pool for 192.168.0.1/24, 172.16.16.1/24, etc. But when I use the same commands to add a pool 192.168.1.1/24, I get:

  SW (config) #ip dhcp pool perimeter network

  SW(config-DHCP) low #address 192.168.1.20 192.168.1.250 high 255.255.255.0

  Illegal IP address range, or subnet configuration tries to configure a pool of network on the default IP interface

  VLAN 1 IP went from 192.168.1.254 to 192.168.0.1 static default.

  Any ideas?

  Hi Frank,.

  Looks like you are experiening, bug CQ145102. There is currently no work around: Sx300 1.3.0 FW Release Notes.

  Problem: You cannot configure IP address 192.168.1.0/24 subnet as an address
  pool, other subnets are allowed. (CQ145102)
  Solution: There is no workaround.
  

  I open a case with Cisco Small Business Support, have your degenerate case and see if you can get the beta FW. The only alternative would be to review your network in order to eliminate the 192.168.1.0/24 subnet.

  Kind regards

• 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.

• 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

• 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

• Client DHCP is unable to get a valid IP address from the DHCP server.

  Client DHCP is unable to get a valid IP address from the DHCP server. I have a home edition of Windows XP attempts to connect to my router wirelessly with wireless or wired connection but I get an error in Event Viewer with the discription DHCP 1007 error message. From what I researched, I discovered that the DHCP service depends on the AFD, TCP/IP and NetBT services. All these services are correctly place and worked very well (even the DHCP service is running without error) but every time I try to release/renew my IP address I receive than DHCP warning in the case where the viewer and I just cannot get a valid IP address of the server (router) I also have one of these verizon wireless G3 usb adapters and it works fine. I also have a good ping back when I try to do a ping localhost (for the closure) I also tried the preinstallation of uninstalled drivers from the adapter/s and nothing works. The only entrees in the registry for DHCP error are also AFD, NetBT and TCP/IP nothing else there, also all the files in the/system32/drivers afd.sys netbt.sys and tcpip.sys in addition to solve the problem, I'll mention that I installed and reinstalled Northon earlier, I do not remember if the problem appears before or after that. I receive also any error or warning in the security log or at least I don't know how to read: P

  Thanks for the information.

  I hope you know that it is risky to connect the laptop to the Internet with no firewall and no antivirus... If this laptop is already connected to the Internet in this State, he is perhaps already infected.

  You said you know the router works because the other computers can connect successfully to it.  You should check the configuration of the router to make sure that it is not configured to limit the number of IP address it supplies, and (b) it is not configured to filter users by MAC address.

  When this laptop is connected by Ethernet, even if he gets the IP address of 169.254.x.y, can you ping the router?  Find the IP address of the router on any computer connected to it by running the ipconfig command in a command prompt window.  The "default gateway" is the IP address of the router.  Run the ping command in the command prompt window as well.

  If the ping is successful, it is possible that you might be able to use an IP address in the correct range for an Ethernet cable (but I doubt that it works for the wireless).

• "Unable to contact your dhcp server.

  I can't connect to the internet.  I'm on a wired connection.  My system is Windows XP Professional with the media center.  I get the 169.254 ip address automatic with the subnet 255.255.  I tried releasing the investigation period, renewing the period of investigation (failed to contact my dhcp server), uninstall and reinstall the protocol tcp/ip (which gave me a false message of connectivity with the automatic ip and the subnet assigned by dhcp), uninstall and reinstall the driver, my dhcp that is activated.  I've tried everything I can think of or find.  I need to some tips and suggestions.  Thank you!

  Thank you all for responding.  I tried all the software solutions that I know and it was recommended to try.  Nothing.  I have only that it is a hardware problem.  I'll install a new Ethernet card and see what happens.

• An error occurred while renewing interface wireless network connection: unable to contact your DHCP server. Request a expires.

  I use an Acer Asspire One with Windows XP. We have wireless through AT & T Uverse. The netbook has an Atheros AR5007EG Ethernet card.

  A number of things have taken place lately: I had not used the Acer for some time and the battery was dead and would not recharge. I could book until when it was plugged, but could not get on the Internet. I found online that the solution to the battery problem was to download a new bios that worked wonderfully and it is now loaded. Recently, our AT & T router died and was replaced. I put the new WEP keys in two other computers, and they connect to the Internet. I can't connect to the Internet with the Acer. I tried ipconfig / renew and get the error message: "an error occurred during renewal of the wireless network connection interface: unable to contact your DHCP server.» Request a expires. No operation can be performed on Local area connection while it has its media disconnected. "On the tab"Choose a wireless network", it shows my network and said"absorbing the network address"but nothing happens. When I do ipconfig I see that there is no IP address.
  I took the computer to Starbucks this morning, ran ipconfig / renew and she acquired the IP address and I was able to connect to the Internet. I brought the computer home and tried and failed to connect. The IP address is back to 0.0.0.0 and the error message appears when I try to renew it.
  I hesitate to make a lot of changes since it was working with a different network.

• Pwerconnect 6224: vlan client computers do not receive the ip address of DHCP server on a different VLAN

  Hello

  I have a prolem routing dhcp requests between the vlan management where DHCP server resides and the other VLANs.

  I have the scenario of base with three VLANS: vlan 10 (management vlan), 20, 30, configured on a Powerconnect 6224 switch L2 mode. This switch is connected to a pfsense router. The router is configured at the package of road between the VLANS and it does it well.

  In Vlan 10, I have a configured DHCP server to use the ip addresses of all the VLANS (10, 20, 30). VLAN 10 client computers receive ip address but not others from other VLANs.

  When I put the ip address in the appropriate range of VLANs manually on computers, I ping the server and I have connectivity.

  This suggests that the problem is with the dhcp package.

  The following is the configuration of the switch:

  The DHCP server stores information that could be useful? May need to configure monitoring ports and something as wireshark to monitor DHCP packets. This would help determine where the package is stopping.

  example:

  Console (config) #monitor session 1 source interface 1/g8

  Console (config) #monitor session 1 destination interface 1/g10

  session mode 1 #monitor console (config)

  right now I don't see anything in the config of the switch that stands out. If the DHCP server is configured for option 82, then you will need to include the following command on the switch.

  Example:

  Trust l2relay console #dhcp (config-if-1/g1)

  But I don't think that's our scenario here.
