Windows 7 Sees The NIC But Won't Pick Up A DHCP Address
May 22, 2009
I put Windows 7 (build 7000) onto a plain-vanilla Dell Dimension 4600. It seems to have found the NIC (evidently an Intel Pro/100 VE) just fine: [URL] .. but I'm not picking up an address from my equally-vanilla Linksys router. With the cable unplugged the network window looks like this:[URL]... and as soon as I plug in a cable it starts doing stuff:[URL]... further confirming my belief that the NIC is working and Windows 7 can see it just fine. But then it doesn't pick up an address. [URL]'ipconfig' in a CMD window confirms that it's using a self-assigned (169.x.y.z) address. This machine was online 2 hours ago with XP, so the NIC, cable, and router are all fine.

I have a strange networking situation. Let me start by saying this situation is on a Domain, and that I am using Windows 2011 SBS and Windows 7 clients.My server has a DHCP range of 192.x.x.150 to 192.x.x.199 - and all other I.P. addresses are static.On a workstation located at I.P. 192.x.x.13 I am seeing an address conflict.When I perform an "nbtstat -a 192.x.x.13" command from the server I am given the logical computer name of a staff members personal laptop.Investigation of the laptop reveals that it is set to DHCP, and clearly the address of 192.x.x.13 is outside of my servers DHCP scope, so this I.P. should never be assigned, let alone in duplicate.I Googled this topic before posting, and it was suggested that IPv6 could be having an adverse affect. I determined this because I performed a ping on the laptop and only got a MAC address back rather than an I.P. address.

My network is set to automatically set an IP, and this has worked semi-okay for the past few days. It disconnects a lot but I can usually go to the Command Prompt and then release and renew my IP, which would normally fix it. So I did that today, only that time it said something about being unable to contact the DHCP server. So I then typed in ipconfig /ALL and it said the DHCP isn't enabled. I tried it again just recently, but instead I get a message saying that the RCP server is unavailable, but the ipconfig /ALL prompt still says the DHCP isn't enabled.

I am having problems connecting my Win7 Sony Vaio to my existing network. I cannot get the Ip address to add it to the DHCP table using ipconfig /all. I can see my connection but not connect to it because of not being able to add it.

I have recently built a new computer, everything had been working perfectly however the ammount of RAM windows displays has dropped from 32 GB to 24 GB, also during POST it displays 24 GB, whereas it had previously been showing the correct 32 GB. When I run CPU-Z and look at the memory tab it shows 32 GB, so I think Windows could be allocating part of the RAM to something without me knowing.

Replaced HP laptop 250GB SATA HDD (Vista) yesterday with new 320GB SATA HDD Win7.Reason for replacing was having to run CHKDSK and Startup Repair a couple of times recently, thinking the old HDD could be wearing out.Win7 sees old HDD connected externally via USB but cannot access. It wants to format the external HDD, but the whole reason for accessing it is to recover data.USB ports are working.Status bar in Windows Explorer says Bitlocker status:off External HDD cable is Y configuration and have tried it with just one and both plugged in.(H > Properties > Tools > Check now > Tried to run CHKDSK on the external HDD but it says "Disk check could not be performed because Windows can't access the disk." Under the Hardware tab it shows the two WD HDD and each says "Device is working properly."Under Change Settings, Quik removal policy (default) is enabled.Under Drivers > Update driver > it has the latest driver.Win7 AutorunKiller said external HDD is safe.Avast and Comodo are running but no security message has appeared. Might it need an exclusion anyway for Comodo?There is no security tab under (H > Properties so not sure if UAC or permissions is involved. BTW, the light on the external HDD blinks rapidly while opening Properties but it takes a long time to display.So, there is where I am at the moment and if you have time to consider a path of resolution for this anomaly.Additional info: I have just connected an old ATA HDD via USB and migrated some data with no problem. Also, I have just connected an older laptop HDD via USB and migrated some data. I swapped the cable from the older laptop to the new recently replaced Vista HDD and it gave the same message wanting to format the 250 GB Vista HDD.

I have a 4 port generic usb hub which I have connected to my computer through a 15ft usb extender (PC on a different floor then monitor). Now when I connect through the USB extender windows 7 does not pick up the driver and gives me a code 43 error, but if I connect the usb hub directly to my computer (not through the usb extender) the driver is found and installed. I cannot see why the USB extender causes windows 7 not to find the driver or show a code 43.

I've just finished my brand new build and am now ready to install Windows 7.
However when I load the disk select custom install and its asks me to select where I want the OS to be installed, I get an error message saying it cant find my HDD and I need to select the appropriate drivers.
I can see my Hitachi 500Gb in the BIOS, I have tried ATHC and IDT settings but still wont work. I have tried factory default setting in the BIOS but still Win7 cannot pick up my HDD.
The LED is flashing also to note that the Drive is working. Also Win7 wont let me format the disk either.

I have an odd problem with my Windows 7 installation. The computer I'm trying to install it on is running Windows XP, and any time I try to boot from the disk (I have it set to be first in the boot sequence), it seems to just skip over the disk altogether and run boot from the hard drive (into Windows XP). I looked into this further, and it turns out that the computer sees the disk as being blank (0 bytes out of 0 total bytes).
When I put it into other computers, it is read fine, and I have even used this disk to install multiple copies of Windows 7 on other computers. The computer that isn't working can read any other disk fine, and has never had DVD-drive related problems. I've even tried copying the files from the Windows 7 disk onto another DVD, as well as a portable USB drive, but those didn't seem to work either (it gave me some error about the disk not being bootable).

I run Win 7 64 bit with Virtual XP. I loaded HP 5400C software into Virtual XP. I attached Scanner and was able to scan/print and scan/pdf. ie everything worked as it should. A week later Virtual XP requested I run 7 updates. Since 7 updates the Virtual XP sees the scanner. When I request "attach" it goes ding dong. When I check again the wording does not change to "release" I think the problem lies with the recent updating. The scanner software reports the scanner can't be found.

I'm curious if there is a way to run a specific program when I choose to reboot into safemode with networking?
Specifically looking to run or make sure the service for Logmein starts. The work I have to do would be best done in safe mode, and of course connecting remotely would be great.

Several months ago my computer stopped picking up any wireless networks. I can connect using an Ethernet cable and a USB wireless adapter. I have troubleshooted and removed my driver and updated software; I even upgraded from Vista to Windows 7 hoping that might fix the problem but it didnt. I am thinking it may be my internal wireless card. So you recommend going to a hotspot to see if I can pick up there? I would think I would have to do that considering the USB adapter picks up multiple wireless networks but my internal one picks up none so I think that already rules out my router being a problem.

I recently ran a system recovery on my Samsung 305V and set it back to factory defaults. Now my problem is connecting to the internet. I have hardwired it to the router, also reset the modem and router several times. I disabled the firewall and tried running in safe mode with networking, everything has failed. I looked in the Device manager and there are no devices in the network adapter category besides two Bluetooth Devices. Under the Other Devices category it shows Ethernet, Network and SM Bus Controllers with yellow caution signs on them, I don't know what these are but I can't update the drivers on them or anything.

My PC is very fast, boot up is fast and when I first installed Windows 7, it used to obtain an IP address almost instantly.....now, after a few weeks use, the machine takes a lot longer to initiliase the networking, once it obtains the IP address, then everything else loads at quick speed and it runs fine.I'm using an ASUS P5Q-E motherboard, with dual Marvell-Yukon Gigabit NICS (although only one is enabled) and a DLINK ADSL modem-router.The router isn't the problem as other PCs connect to the network fine - And I'm sure it's not the network cards as I've downloaded and installed the latest ASUS approved version of the marvell-yukon WIN7 driver.I've experimented with installing / uninstalling the NIC, letting it use standard WIN7 drivers instead, trying a couple of different versions of the NIC driver but all to no avail. It's really annoying, as my PC is very fast normally and this is the only thing causing a slow delay on boot (it takes about 20-30 seconds to initialise DHCP).

I used to be able to access the internet on this computer - on a small business server 2003 - on the Network Sharing center, it shows that I am connected to the network (doesn't matter if I'm on wireless or wired same issue) it shows an x on the display for internet. I checked the gateway and it is the same for the other computers that are on the internet. No problems anywhere else connecting to internet. I don't have any spyware/viruses. I can access files on the server and other pcs no problem - just won't let me on the internet. I read somewhere that it could possibly be SP1?

My internet connection shows 'no internet access' even though my ISP shows the connection is coming into the house just fine. I usually use a router (NetGear-WNR3500U) but I right now I have the Ethernet connection plugged directly into my PC. I tried directly plugging into my laptop and the internet works just fine. So I know the problem resides in the PC.
Some troubleshooting things I have tried.
-Power cycled my modem, router and PC.
-Repinged my connection from my ISP(Comcast Xfinity)
-Used the reset option on the router and the modem
-I was walked through the internet options needed with the tech support from my ISP to make sure DHCP was enabled and every other setting was correct, and he cleared me that all settings were correct.
-Tried ipconfig commands to /renew and /release my IP When I tried ipconfig /renew I get the error 'An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server'
-Restored my PC to a restore point where the Internet was working
All of these options did not work.
What I think the problem is and I am not sure how to fix it, when I run the ipconfig /all command my Auto configuration IPv4 Address shows 169.254.112.76 which I was told is a router IP address even though I am plugged directly from the modem to my PC with an Ethernet cord. So I think that's my problem? But I am not sure.

I have a Razor mouse ( the Lachesis) which has the ability to store profiles -of polling rates and DPI- and switch these profiles as it sees the desired program. I use two profiles. One is for the "Steam.exe" for my on-line gaming. When I launch Steam, the mouse sees the exe, and switches to this max polling/DPI profile. The other profile is the "Normal" profile which is set at a much slower, less twitchy speed. On XP, I was able to find the Windows "Explorer.exe" in CWindowsSystem32. I set this as my switching exe.and it caused the mouse to switch to the "Normal" profile when it saw the desktop. I can't find the "Explorer.exe" in System32 in Windows 7. Is there no such thing in Windows 7 (Enterprise) or is there another exe. I can use for the same purpose of switching, on seeing the desktop?

I have a Samsung RC512 SO2 Netbook w/ Windows 7 Home Premium 64bit.My Computer has two videos cards in it:
1) Intel(R) HD Graphics 3000
2) NVIDIA GeForce GT 525M
Currently it is using the Intel card for my built-in display on the laptop.The max resolution is only 1366 x 728. I am looking for any way to jack up the resolution.Is there a way to switch the built-in monitor's video card to the GeForce, with hopes that it offers a higher resolution?The only thing I could find is a way to utilize the Nvidia card for another monitor if I plug it in, but not for the built-in display of the laptop.

My computer's Stereo Mix option (Windows 7 Home Premium, 64bit, HP Pavilion p6330f) USED to be able to record my computer's audio fine, but now it no longer does that. It rather chooses to record exactly what my headset records. It may be worthy to note that I think it may have stopped working because of my new headset (Turtle Beach X11 series). However, going on this theory, I tried to disable the microphone and even use a different kind of microphone, but it still did not work.As I mentioned, I've tried disabling the mic and have looked through the options available on Stereo Mix and just can't seem to figure out why this is happening. I just want to be able to play music back on my microphone when I'm talking to friends on Skype.

My laptop with Windows 7 home premium has developed a problem recently. When it tried to log on to the home wifi.
1. It will connect but the DHCP insist on connecting to a specific IP address, in this case (192.168.0.58)
2. Then tells itself that the address is already in use on the server, I looked at the router log, it never called and the 192.168.0.58 is unused.
3. Then it will fail to call for another IP address.
4. So the adaptor will show connected but no internet.
I have tried:
1. rebooting the router, even changing the SSID. Same deal.
2. Assigning a static IP on laptop. Worked! but the second that I change it back to dynamic, same ole problem.
3. Even uninstall the wifi adapter, then reinstall it. Worked for a few minutes, then same problem again.

I have a printer connected to my network via ethernet. It is a Brother MFC-J825DW
PC1 - no problem - I find and install the printer using the "add a printer" option under "devices and printers" that I have used without issue in the past.
PC2 - PROBLEM - when using "add a printer" the correct printer is identified but will not install. The computer seems to hang when searching for the IP address.
--- Attempt 1: manually enter the IP address for the printer. DOES NOT WORK PC hangs at install.
--- Attempt 2: downloaded Brother utility which correctly identifies the printer and its IP address but "add a printer" (through wizard or manually) still will not work.
NOTE: Printer is set to "share this printer"

I'm using Microsoft Virtual WiFi Miniport Adapter for ICS across my laptop and phone. But I don't find a way to disable the default DHCP&DNS available with ICS.
I'll runn Dual Server DHCP&DNS () on my own. Which will get me better control over the DHCP leases and all DNS forwarings along with the full log. For this I need to shutdown the default one. It is possible, because Connectify does the same.
