MacBook Air :: Unable To Get IP Address From DHCP Server

Jan 9, 2011

I've recently purchased my first Mac (the new 13.3 inch air model). I seem to be having a bit of a problem with wireless networking, though. It seems that my Mac will reconnect to my wireless network perfectly after resuming from sleep mode just fine for a few days, but after those few days, it will mysteriously stop being able to get an IP address from the DHCP server (my wireless router). My PC is able to connect to the network just fine and always seems to be able to get a new address, but the Mac just loses the ability. I have found that the only way I can get the Mac to start grabbing an IP address from the router is by going into the router settings and changing the RIP mode to a value other than what it currently shows. I generally try to stay in RIP_2B mode, but I change it to some other random value whenever it stops connecting.

OS X Server :: Unable To Use DHCP With Windows XP

Jun 29, 2005

I have a Mac OSX Server (10.4) connected to a switch with various Airport Express terminals around the place. Macs can connect to the network wirelessly (with 128 bit WEP) and WIRED totally fine... but when I try and connect a windows PC either using wireless or WIRED... an IP address isn't assigned. Windows just says "Limited or no connectivity"...

Hardware :: Airport DHCP Fails To Get Address (Mac On Windows Network)?

Jun 7, 2006

I am a comitted Mac switcher trying to put my lovely new MacBook onto the office Windows network. I can connect to the office wireless network (WEP key etc) and the little radar Icon in the menu bar lights up. However, I cannot get the MacBook to obtain an IP address via DHCP. I just keep getting the default self assigned address (169.....).

However, when I connect to the network via a cable using the built in ethernet connector, I get the DHCP address just fine and everything works OK.Also, if I assign an IP address manually to the wireless card (checking it is a free address!) it accepts the settings but I cannot network, not even a basic ping of another machine on the local internal network (all our internal machines are using 10.0.0.x addresses and 255.255.255.0 sub net)The DHCP server is not in the wirless router but is a Windows server machine.This is driving me crazy. I have called Apple care and they just dont want to know because there is a Windows machine in the mix. I expected better from them,

OS X Server :: DHCP Grab My New Addresses

Mar 8, 2007

The service shows running but will not give an IP address to Mac or PC. As the leases are running out on the machines they are not being renewed. I restarted the service and then the server. Then I reset the DHCP Client list.I turned on a computer lab so that they would all grab a new address.... none of them did. I logged on to a computer and told it to renew its DHCP address and nadda. If i assign a static ip they are fine

Lion Server NAT Destroying DHCP

Mar 29, 2012

I have recently purchased a USB Ethernet adapter so I can setup NAT on lion server that runs on a MacBook. I was shocked when it blew away my DHCP Config after I set up NAT, but I stuck with the scope it chose and added the correct DNS and gateway settings.Whenever I start DHCP now, the logs tell me the Config cannot be found, and it blows away all of my modifications to DHCP. On top of that, it won't hand out any addresses.If I stop DHCP, the system logs start telling me that "natpmpd" has started, and then it begins to hand out addresses. The problem with this is, I can't make any changes to the DHCP settings it uses, which means my clients are now getting the incorrect settings for the gateway and DNS.Also, when I modify the Scope with DHCP stopped, the logs tell me it cant update the subnet because it was not found.

MacBook, Mac OS X (10.7.3)

Mac OS X Lion Server :: Get DHCP To Update DNS?

Apr 14, 2012

I have setup OS X Lion server to act as the DHCP and DNS server for my local network. DHCP provides gateway address and the local DNS server address.   DNS is set to forward to my ISP DNS servers. 'A' records and 'PTR' records have been created for the various servers on the network and I am able to resolve the servers via dig by name and address. I can also access the internet without issue. DHCP is handing out IP addresses to Windows clients on the network but I am unable to locate the machines with DHCP addresses in DNS either by IP address or FQDN. The windows clients are able to access the internet without issue. Looking at the DNS log there does not appear to be anything recorded when the DHCP address is allocated. Is there something special that needs to be setup either in DHCP or DNS that will allow DHCP to record the host and address details in DNS?

Mac OS X Lion Server :: Email Address Requires Host Name In Address Field

May 5, 2012

I'm trying to setup mail on Lion Sever (7.3). The only way I can get it to accept incoming mail is to specify the whole FQDN of the server in the address.For example the domain name is example.com and I have a user set up called john. Sending mail to john@server.example.com works.

But sending mail to john@example.com (which is what I want) returns an error:
554 554 5.7.1 <john@example.com>: Relay access denied (state 13).

For internal DNS, I have:
example.com - primary zonemail.expample.com - alias server.example.comserver.example.com - 192.168.1.2 [URL] - alias server.example.comMX record [URL]

I see references here to problems in mail on 7.3 but not this specific problem.

OS X Server :: Server's Static IP Address Used By Another Device?

Nov 4, 2006

The following error comes up on the server's screen when I turn on the stations:"IP 10.37.102.21 is used by 00:0d:95:34:ee:60"Another device in my room or building is using the server's static IP address, this causes connectivity problems. I loose connection to the server. How do I find out what device is causing the problem and what do I do to resolve the issue? I am afraid it might be the CISCO 290XL switches used in the lab. I used ARD to check the Ethernet ID's and didn't come up with any workstation using that Ethernet ID or address.

MacBook :: Using Wireless Shenanigans - Changing Back To Dhcp?

Jul 28, 2009

I recently got a white macbook while i am deployed in iraq, and our wireless signal here kinda blows, but at least it works. The only issue i have, seems to be that when i am connected to an access point, my macbook will randomly loose signal, and i end up having to go into the airport preferences, change from DHCP to BOOTp, and it will refresh, then come back on. If it looses signal again, i just change it back to DHCP, and then it works again.

MacBook Pro :: Ethernet Dynamic DHCP Not Working On Mid-2010 With 10.7.3

May 14, 2012

Ever since I upgraded to 10.7.3, my mid-2010 cannot connect to to internet via Ethernet any more (wireless works fine). 

Basically, the Network utility GUI shows that a correct IP address has been assigned via DHCP, but I get no internet. 

If I now check the output of 'ifconfig', I see 'en0' having a local IP address assigned, i.e. 192.168.1.1 or similar. 

Seems like a software bug of some sort. Is it getting fixed in 10.7.4?

When trying to send an email on my mother's .mac account the following error appears. (Her account is biosophy@mac.com). - The message can't be sent because the server doesn't recognize "'biosophy@mac.com"-. I'm wondering if this is because there is an apostrophe after the first quotation mark. If so, how did it get there and how could it be removed?

OS X V10.6 Snow Leopard :: How To Remove Server Address

Apr 10, 2012

I have a MacPro with Snow Leopard.  How do I remove "server addresses" where other computers are no longer in existence.  When I go to "Go/Connect to Server" I have some addresses which are no longer valid.  I can highlight them in the "Favorite Servers" list and hit "Remove" and they will disappear only to come back the next time I open the "Go/Connect to Server".   For example, one of the server addresses is "smb://xps630i-PC/ddrive" and was used to link my MacPro to my PC.

OS X :: How To Create A Network Dhcp

Nov 26, 2010

When we share internet connection through ad-hoc wireless network, each individual connecting to our network will be assigned with an unique IP Address and other required fields will be filled with proper data(Gateway and ..).

I used this feature to access my iPad through wifi, and had no intention of sharing an internet connection.
Now that I don't have an internet connection to share, my computer doesn't give any IP to my device, therefore my computer is unable to see my iPad on the network.

I also tried "Create network" feature of mac, but again, since IP addresses have been assigned by self, I'm not able to see my iPad on the network.

OS X :: Network Can't Locate IP/Router Using DHCP?

Having trouble on my mac while trying to connect to the internet using the built in Ethernet.

It says under network: Built in Ethernet is currently active. Built in ethernet has a self assigned IP address and may not be able to connect to the internet.

I hit the IPv6 and/or DHCP and it locates a IP just not a router number. Is this what is stopping it from connecting? Please help as I have an AP test I would like to study for....

OS X V10.7 :: Airport DHCP Don't Update Lion DNS

May 12, 2012

I own a MacMini Server in my home network with Lion Server installed. I configured the DNS Service with a primary zone, providing nameserver (MacMini) etc. Server Admin tool create also a reverse zone 0.0.0.10-in.addr.arpa (my IP Range is 10.0.0.I own also an Airport Extreme Base Station (4th Gen) acting as DSL Modem, DHCP and NAT and creating 2 Wireless networks (private and public network) and it's correctly set up for internet access... In AEBS settings the DNS Servers are 10.0.0.3 (MacMini) and 8.8.8.8...With these settings everyting works fine but all the devices (other Macs, windows PCs, etc.) cannot ping each other... The only machine they can ping is obviusly the MacMini because in the DNS settings i punt manually a machine (A) record...

My question is: is possible to setup Lion Server to dinamically update DNS records using AEBS DHCP entries and reservations ? If possibile i don't want to add all the record manually and I don't want use the AEBS only as an access point...

Windows On Mac :: XP SP3 Stop DHCP To Work Properly

Jul 6, 2010

We have some Education iMacs that I am having some problems with. XP can be fully up to date (except SP3) without any problems, they are connected to the domain, get an IP address, correctly sync time and process group policy settings at a computer level prior to the logon screen. All this is using the ethernet port (not wireless). As soon as SP3 is applied, they don't get a DHCP address until after login, therefore they don't sync time, process policies etc. If I uninstall SP3, back to working. I have reproduced this several times on different Macs (we have about 90 that are exhibiting this). Tried different version of bootcamp drivers.

If I reserve the address in DHCP, it doesn't make a difference. I seem to only have 2 options:
1. Manually enter an IP address in Windows (this is too time consuming)
2. Leave SP3 off (this means WSUS 3.0 SP2 won't work)
Is there a newer ethernet driver outside the bootcamp package?

I can't even upgrade the MBP because I have no ethernet cable and can't plug it in to update it. I can do to get it to work?

OS X :: Piggy Backing Onto Wired Or Wireless Router - Setup Options - DHCP?

May 4, 2010

I have an additional question about the Airport Express. I am interested in buying one but don't want to commit until I get a few questions answered.

1. I own a D-link wired router and a d-link wireless router. I have been tempted to buy the express, hook it into my wired router and run wireless off of the apple. I want the express so I can run itunes on my stereo from anywhere in the house.

Would there be any advantages to me using the wireless router in conjunction with the airport express instead?2. I am interested in the DHCP comments from above. If I turn off DHCP on the airport express then any friends who come over to use the wireless internet will need to be personally configured. Could I just assign the Airport Express a static IP address on the wired router, keep a DHCP on on the express for my friends and turn off DHCP on the wired router?

3. I have a PS3. I don't want to slow my gaming speed down. I intend on plugging the PS3 into my existing router (wired or wireless router, I will have it wired though) Will daisy chaining the express off of the router slow down my PS3 connection when other users are not using it?
