MAC address on boot.
Since I installed my SATA HD my boot time has doubled because of Client Mac Address. Before when I started my computer it would go to the screen with the BIOS version and graphics, then the Corecell screen the it would go to the Network screen and finally the WIN XP startup. Now it is all the same except after the network screen it goes to :
Intel UND I PXE 2.0 (build 082)
Copyright (shows 3 different years) Intel Corperation
VIA Rhine II Fast Eithernet Adapter
Client Mac Address here it shows a address
DHCP
PXE MOF
It stays on this part for about 45sec then it finally goes to the WIN XP startup.
DOES anyone know what this is? Is there a way to get rid of it? I do not need the Intel Corperation screen on my computer.
That was it. Is there anything that you don't know about computers? Thanks for the help it is always appreciated.

When you installed iTunes on your work computer, then connected your iPad to that computer, it wiped what was on the iPad, then put the iTunes library (nothing) from the work computer onto the iPad. You can try copying the iTunes folder from your home computer over to your work computer, but since the apps were bought with a different account, they may not load or update properly.

T61s, T60s & older model unable to PXE boot to SCCM (MAC address problem)
Hi,
We have a series of T60, T61 & older machines that are unable to PXE boot to SCCM. The T400 & X series & other newer models can boot just fine.
After checking further, we realised that only a certain range of MAC addresses are unable to pxe boot i.e
00-1A-XXXXXXX
00-1C-XXXXXXX
range.. all the other range of MAC addresses are fine to boot via network.
The error when doing network boot is "bad or missing discovery server list"
Also, we are running on SCCM 2012 at the moment. Our branch office who is running SCCM 2008 can have all the machines - regardless of models & brand boot just fine.
Any ideas? Much appreciated.did it obtain IP address from DHCP server? is DNS server address is configured in DHCP scope? can you ping using IP address?
if drivers are proper will suggest to update it in boot media & enable command line support to make it easy for deployment & troubleshooting.

PC22224 switch fails on boot with message "Invalid switch MAC address"
Ok moderators, I know this is a nonsupported product, but you moved all Switch messages to the archive. This seemed to be the most appropriate folder for it. Hope that's ok?
I have a NEW (can you believe it?) PC22224 managed Cisco/Linksys switch with a problem. When it boots, it passes all tests until it is almost ready to run, then I get this message:
Checking file integrity..... Done
Decompressing Code Image.... Done
System PANIC.....
Invalid switch MAC address
Does anyone know how to correct this problem? I can find nothing on it anywhere on the web.
Thanks in advance!

Can't change MAC address of my wireless card on Windows XP
Dear Forum Members,
I have recently bought a notebook, Lenovo IdeaPad G550L (I haven't found section for the G series here on the forum) and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly changed MAC address. I installed the recommended driver, available from Lenovo's website, version 5.10.38.14. I tried the common way to change the MAC address, went to Control Panel -> Network Interfaces -> Broadcom Wireless Network Adapter -> Configure... -> Advanced -> Locally administered MAC address, and changed it to a different address (without ":" or any separator characters). Unfortunately this common solution won't work at all. Although, no error messages are produced when changing it (so it seems successful) my wireless router shows me the original MAC address of my integrated wifi card. Tried to restart my computer, my router, everything.
* Tried different drivers, downloaded a driver from HP which had a separate wireless configurator, Broadcom Wireless Utility. It worked like the driver from Lenovo (except this one hasn't got the utility), but I was still unable to change my MAC address.
* Tried a different driver from SoftPedia, version 5.10.79.14 (this is newer than Lenovo's), it didn't work either.
* Tried Nathan True's MACShift utility. It seemed to change the MAC address, but my router showed the original, so it didn't.
* Tried to look for official Broadcom drivers on www.broadcom.com but found nothing for BCM4310.
* Finally, I booted my alternative OS, the latest Ubuntu Linux, and used the kernel driver b43 for my wireless adapter. I tried to change my MAC address using the command ifconfig wlan0 hw ether .... and connected to my network. It worked, my router showed the changed MAC so the hardware (or the firmware) is capable of doing this by the right driver/firmware.
I tried to address Broadcom with the issue, sent them a letter like this post they replied that they are not competent, they wrote the following (I guess this was an automatically generated message because it got back in 10 seconds ) from [email protected]:
"As the chipset supplier, Broadcom provides driver support to our customers - the manufacturers of wireless devices - that ultimately provide products to end customers, such as wireless LAN vendors, cable modem vendors, and notebook providers. It is up to these manufacturers to provide product-specific drivers and software support to their end customers. Please contact the manufacturer of your wireless device for their current drivers"
Then I addressed Lenovo with the problem, their answer:
"Dear ******,
Thank you for contacting Lenovo, the makers of ThinkPad and ThinkCentre products. As I understand, you have purchased a Lenovo IdeaPad G550L and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly change MAC address.and you would like to know is there an official driver for Windows XP that allows you this basic feature like b43 in Linux. We apologize,Please do speak with our Idea pad technical Team at 877-453-6686 Option 1-2-1-2 for further assistance.
If you have further questions or concerns, please feel free to contact us at 866-42-THINK (84465) option number 2. We will be happy to assist at that time.
Once again, thank you for contacting Lenovo.
Sincerely,
Lenovo Websales/CustServe"
So this means I should call them and spend extra money for phone bill of international calls because of their fault of providing a basic feature that is to be expected from every single wireless card in the market. Should I believe that a guide over the phone is more efficient than a step-by-step solution or a link to an alternative driver? I'm getting kind of disappointed. At least they have understood (or copy-pasted) my problem, dutch comfort though.
Any ideas? Anyone experienced the same problem and solved it? Is there an official (or even unofficial) driver for this device for Windows XP that allows me this basic feature (like b43 in Linux)?
Thanks in advance,
str4ngSYes, I have posted this thread to different forums after I realized that Lenovo "customer care" is not likely to help me out and even wirelessforums.org members couldn't come up with any ideas for days, that's why. I have already written that helper applications like SMAC (or etherchange or macshift) don't work, because they do the same thing in the system as I change it in the driver panel, so they use the same method which simply does not work.
Locked? Definitely not. If yes, why can I change the MAC of my adapter under Ubuntu Linux using b43 open-source driver if it's really locked? Or you mean it's locked from software, because Lenovo or Broadcom didn't want their users to change their MACs or they just forgot to release a fully-functional driver? Well, then I would like to have a driver in which it's not locked, because this is a basic feature of my adapter of which the hardware is capable.
I have already contacted Broadcom, see their (automatically-generated) answer in my initial post, but I will try to do that again with more foresight. -
ARP table not populating mac address for previously reachable IP address
Router has been online and working fine with one BGP neighbor for almost 2 years and no downtime. 2 weeks ago, added a 2nd BGP peer. Everything worked fine for 2 weeks, then all of a sudden yesterday the 2nd BGP peer is disconnected and does not come back. ISP checks and sees everything looks fine on their end. We cannot even ping each other now.
Upon investigation, the ARP table is not even populating the MAC address for the BGP peer IP anymore (same local subnet). Stays "incomplete" in the table no matter what we do, including clearing arp table, changing IP address, etc.
Plug a laptop directly into the 2nd BGP peer FE port and replicate the IP addressing. Laptop cannot ping Router, but Router CAN ping laptop. Check ARP table, but STILL no mac address assigned and now not even the ARP table showing "incomplete".
Thinking it could be the FE interface, switch to the 2nd FE interface and perform same laptop test, this time with arbitrary IP addressing. Now cannot ping each other, no MAC in ARP table.
End up rebooting the router and lo-and-behold, everything is working normally again. 2nd BGP peer peers up instantly.
I should also mention that the 1st BGP peer worked flawlessly throughout, taking all the Internet load and having no issues throughout.
Also, the FE ports for the 2nd BGP peer are on an HWIC FE card plugged into the router. The 1st BGP peer is plugged into the built-in GE interface. 2901 running: c2900-universalk9-mz.SPA.151-4.M4.bin
Lastly, no router resource issues, no error messages, no logs. Just the BGP peer disconnecting.
I have never, in 20 years working with Cisco routers seen something like this before. This is the most fundamental aspect of IP and Ethernet that was not working.
Has anyone ever seen this behavior before??

Request for info regarding MAC address population in computer objects
Hi,
I am trying to determine how MAC address information is populated in computer objects. I had assumed initially that the hardware scan would be used, but observation shows this information
to be obtained prior to any hardware inventory.
I have laptops that are primarily connected via VPN, and before long their objects lose the internal network interface's MAC address. When I try to rebuild them, they fail to PXE boot. I have
found that importing a CSV of host / MAC / SMBIOD GUID will update the object (rather than having to delete and recreate it) which works temporarily. The MAC will eventually disappear, and the device fail to PXE boot.
I have thousands of these devices to manage, and it is already difficult enough having a CAS and two primaries (the windows Deployment Service on a DP only cares about devices in the DPs primary
site, and so devices that move site are a real pain already, try finding that anywhere in the OSD reference documents!)
I'm assuming now that this information is pulled from the actual client-server connection, and therefore is dynamic(ish), like IP information. If this is the case, more detail around that process,
where to find evidence of that process occurring would be very useful.The MAC is updated by hardware inventory and heartbeat discovery.

How to change the mac address of thunderbolt to ethernet adapter?
Hello everyone,
I am using Macbook pro retina display 2013 version. I have bought a thunderbolt to ethernet adapter in order to connect my Macbook to LAN. But in my area there is a shared line and I have to clone their mac address to my Macbolok. I could not change the mac address of my thunderbot to ethernet adapter. Can anyone please tell me how to change the mac address of thunderbot to ethernet adapter step by step??
Thanks in advance.Open terminal and type the followings;
1) sudo ifconfig bridge0 ether xx:xx:xx:xx:xx:xx(it will be your new mac address)
2) Type your password to confirm
3) ifconfig bridge0 |grep ether (to see if change is successful)
PS: *This should with your thunderbolt adapter, but its not working usb to ethernet adapters without installing required drivers.
** You may need to do these steps every time you boot your mac. -
In a video that I watched a few days ago someone explained a basic process of booting up a switch and how a switch learns mac addresses. He said something that I would like to discuss. I know... it is not important but want to clarify :)
PC1---SW1----PC2
PC1 wants to send sth to PC2. In the video it was said:
'a frame arrives at SW1 and SW1 learns the mac address of pc1 but it does not know the mac address of pc2 so it will flood this frame to all ports'
My uderstanding is that it all starts with an arp message: pc1 does not know the mac address and sends an arp and it will allow the switch to learn both mac addresses: pc1 and pc2. I am too lazy to do it in wireshark but did that in PT and that's what I saw as well. After the arp - switch learnt both macs and did not flood the frame.
Am I correct? I know it is not important but... ;-)It may be possible that there was some aspect of the switch environment in the video that would change the behavior (perhaps something like a long timer for the ARP cache in the PC and a short MAC ageing timer on the switch). But in general you are correct. PC1 would send an ARP request as a broadcast, the switch would learn the MAC of PC1 and forward the ARP request. When PC2 sends its response to the ARP request the switch would learn the MAC of PC2 and forward the ARP response. So the switch should have both MAC addresses when data traffic begins to flow.

DHCP Server with the strange MAC address at the same time. This MAC address is HEX IP address!
Server version: Windows server 2008 R2 Ent.
Structure of DHCP scopes: Two DHCP server 50% to 50% all allocation for per scopes.
Question: Sometimes the DHCP server
allocate the IP address at the same time to the a strange MAC address per IP address, the type is "DHCP/BOOT", it cause DHCP scopes out of space at some time point. We need clear up them manually.
I found strange MAC address in HEX is the IP address which the server allocated.
Someone meet the issues before, any solution for this ?
Thanks !

31302e3139392e3139312e31363200Hi,
According your description, this may be caused by virus or malicious client.
Please try to perform a network capture on your DHCP server. Then find the device which send these malicious discover messages.
To download Network Monitor, please click the link below,

To prevent this issue, you may implement NAP Enforcement for DHCP.
Here is a checklist of configuring NAP Enforcement for DHCP,

Use Cisco ACS to verify MAC address for VPN User
Question: I want to have the MAC address of a machine checked when the user is logging into VPN Client.
For example:
User opens VPN client-->Clicks connect-->types in User/Pass which gets passed to ACS (part of what should be sent is the MAC address)---> ACS responds with a yes/no on user/pass and whether the MAC address is right)Hi Pete,
I have found out in some of my testings that If a PC doesnot genareate any kind of traffic and is totally ideal and once the MAC-address table ages out, it doesnot show its MAC untill the PC generates some kind of traffic.I guess this is what you must be seeing.
I have oberved one more thing that If I connect a fully booted PC which not generating any traffic to a switch port it doesnot learn its Mac-address untill its generates the traffic. This is what my obeservations is and that what I believe in most of the cases.
i dont know whether that answer your question or not but it could be something closer. I think there will be some who can put some more ligth on this.
regards,

My mac won't boot up, just has a white screen with a blinking ? mark, any suggestions?
my mac won't boot up, just has a white screen with a blinking ? mark, any suggestions?
this usually means the software and hardware can't find each other for whatever reason the following article addresses this issue:
http://support.apple.com/kb/TS1440
can also do apple hardware test, following article on that:
http://support.apple.com/kb/HT1509
if you can't access the apple hardware test in the above article you can also do fsck command to check the hardware as well, following article tells how to do that:

hopefully one of these articles helps w/ resolution!! -
WGA54G V1 mac address is somehow changed. And i can't get the dns to wor.k.
I have an old WGA54G. V 1.0, I think.
I pulled it ou to use it. I plugged it all in and into ethernet on my switch, it booted up ok and it was connected to my dsl router.
I noticed it's MAC address in my router.Same as the sticker.
So all that worked.
I went into it with it's IP address and it all looked normal, it had it's own MAC address listed on the web UI and all.
I put in my local wep key and told it to connect to my wireless so I could take it and plug it into the XBOX 360 in the livingroom.
That all seemed to work OK too. It connected to the wireless.So far so good Then it became unresponsive. Now this is connected to ethernet and also wireless.
Connection timed out
But then I noticed the MAC address listed on the web UI is well, mostly blank.
1f:c0:00:00:00:00
I looked in the router again and it's listed as being connected wired and the MAC is correct.
So what's up with this mac address as listed on the web UI?
How can that be changed back to normal?
I reflashed the unit to the latest firmware.
I hooked it to the Xbox 360
The Xbox 360 liked it and asked me what the wep key was, all of which I had put on that unit before I hooed it to the xbox 360. But it connected.
It seemed ok but it couldn't get an IP from the DHCP so I gave it one outside my DHCP range. Then it complained it couldn't get DNS from the router. So I gave it the google public DNS 8.8.8.8 and 8.8.4.4. Then it complained it couldnt' find Xbox Live in DNS. I tried my ISPs dns. Same error.
Can anyone shed light on this? Am i doing something wrong?Did you reset the WGA54G after updating it with the latest firmware? It is recommended to reset the device after upgrading the firmware. Try to reset the WGA54G.
Here is the steps to reset the router:
Push the reset button on WGA54G for 30 seconds, turn off the WGA54G wait for 30 seconds and then power it on. Power light should blink when you perform the reset process.
Before trying to connect your Wireless-G Game Adapter to a wireless network, please know the following: SSID, Wireless Security and/or Network Key. Make sure that the Xbox™ works when wired to the router before proceeding.
Here is the link for setting up Wireless-G Game Adapter: http://www6.nohold.net/Cisco2/ukp.aspx?pid=93&login=1&vw=1&app=search&articleid=4536&userrole=Linksy...
