Local Area Connections and Device Manager blank

I'm running a Windows Server 2003 Domain Controller with Windows 7 machines underneath it. Both on the DC and the clients the Network Connections is blank and there are no Devices in the Device Manager. I found numerous other articles having me check services,
GPOs, Registry settings, etc. However, I can't seem to make progress on resolving this issue. Any pointers would be appreciated. Thanks.

Hi,
Based on my research, the blank Device Manager issue is usually due to you have a critical Windows service disabled or your permissions in the registry for the Device Manager
key are corrupt. Please make sure that the Plug and Play is running in the Services. In addition, please check the permission of key blow:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum
Please right-click on Enum and choose Permission, then make sure that you have set Everyone with read permission and System with full control permission.
In addition, since your network connection was blank, you can also try to delete the Config key in the following key
to clear the configuration cache:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network
Windows automatically recreates the key if you open Network Connections folder or restart your system.
Best regards,
Susie

Local Area Connection

Every time i plug up the router it says limited or no local area connectivity
and when i put the modem back on it works so wats happening?
Model: WRT56G
I have windows xp

As it shows "limited or no connectivity" on Local area connection...... it means itis not getting valid Ip address from router .....
Power cycle the router for 20-30 seconds ...... check that you are getting Ip address or not ...
If not ..... change the port from the back panel of router ......
Or lower down the card speed of Ethernet NIC to 10 Half Mbps ....
If still you are not getting valid Ip reset the router for 30-40 seconds & see whether there is any Ip address or not....

What does the "Local Area Connection* 12" mean?

using the commands below(win 8.1 professional):
netsh wlan set hostednetwork mode = allow ssid=myWifiName key=myWifiPwd
netsh wlan start hostednetwork
In Windows 7, the commands will generate "Wireless Network Connection 2"(I think the reason is that there already exists a connection called WLAN. So it starts from number 2).
In Windows 8.1, the commands will generate "Local Area Connection* 12"(I could not figure out the reason why the number is 12 and what the asterisk means???).
I could not stop myself from thinking why the number starts from 12 and what the asterisk means? I could not get useful info from google. So I registered an account. Could you help me please ? thanks.

Windows makes several "simulated" network adapters for various purposes. For example, if you're on an IPv4-only network, but you want to connect to an IPv6 computer on the internet, Windows can create a simulated network adapter that tunnels the IPv6 traffic
through your IPv4 network.
There are actually quite a few of these simulated network adapters. Since they usually quietly take care of themselves, and they don't correspond to any actual network hardware that you (the end-user) can see or touch, Windows will hide them by default,
to avoid clutter.
Now suppose Windows just started numbering all the adapters with the same naming scheme ("Ethernet 1", "Ethernet 2", "Ethernet 3", . . ., etc.). Then by the time you actually install your actual NIC, it would probably get a name like "Ethernet 7".
But since Windows hides the first 6 network interfaces, you'd see a listing that only includes one NIC: "Ethernet 7". And you'd probably say "stupid Windows doesn't know how to count."
So instead, we have two numbering schemes. Real, physical NICs get numbered "Ethernet ###" (or "Wi-Fi ###", etc.) while all the hidden network adapters get "Local Area Connection* ###". That way, the NICs that you see will be numbered
starting from 1, even though there are a big pile of hidden network interfaces that were installed first.
What does the asterisk mean? The asterisk used to be the signal that the NIC was a hidden NIC. Older versions of Windows named all visible NICs "Local Area Connection ###", and hidden ones were distinguished by adding an extra asterisk.
These days, we try to avoid using nerdy jargon like "Local Area Connection" when talking to you, so we changed the naming pattern to "Ethernet". But since hidden NICs don't matter, we kept their old naming pattern with the asterisk.
If you're curious, you can see all the network interfaces on your system with this PowerShell command:
Get-NetAdapter -IncludeHidden
(I'm the engineer that invented and implemented Windows's current NIC naming policies.)

P7N 750i SLI platinum, no Local area connection

Hi,
i have something very weird with my second p7n 750i platinum mobo(first one i had to send back because it didnt post), i dont have a local area connection in network connections and i am using the onboard network controller, the only thing i see in there is the firewire.
owkay first things first, i installed windows SP2 and updated it to SP3, then did the nforce drivers that came with the mobo, got a BSOD with those on the nvgts.sys error for sata drives and the ethernet controller with those nforce drivers installed correctly and i had an local area connection visible in network connections(could see this in safe mode), but since i couldnt boot into normal windows with BSOD i deleted those nforce drivers and downloaded the latest from nvidia 8.43.
i installed the nforce 8.43 drivers just the ethernet part without errors in normal windows since i was able to boot back to it.
Now i dont see a Local area Connection but i do have an active connection(i get ip address from dhcp and am able to do everything on the internet and network)
first thing i tried then was again removing the 8.43 drivers and install the drivers from the cdrom again without the sata stuff just the ethernet drivers but then the network adapter didnt work at all so i went back to the 8.43 drivers with the same result, i have a connection, i just dont see it
ive tried everything i could think of to get it to show up but havent found anything,
maybe any of you can help with this
the image shows what i mean on the right side and you can see in device manager its there and also in ipconfig
http://users.skynet.be/Sabre/nolan.jpg

Everything is fine now
i did another fresh install but this time with a dutch windows XP SP2 not english and now i do have a LAN icon in network connections and im using the same driver installers as before, very strange.
and to answer NovJoe: on the english xp i could install all drivers without errors, from nforce i only installed ethernet drivers and SM bus controller, only thing was that the ethernet controller was not fully recognized by windows i think so it didnt show it in network connections but how or why i have no clue.
As you can see in my screenshot in the command window next to ethernet adapter it should have said Local area connection except it shows a bunch of numbers but its fine now, ill stay with my dutch win xp then.

Local area connection doesn't have valid ip

I have a Touchsmart 320-1030 that belongs to a friend. Everything was working fine then for no apparent reason connection to the internet was lost. They have contacted their isp and gone through all troubleshooting with them. All other equipment (ie laptops, phones, ect..) connect and work fine. The windows troubleshooter offers no help and says local area connection doesn't have valid ip is the reason it won't connect. This is true when trying to connect wired or wireless. I piddle with fixing computers as a hobby so they have asked me to see what I can do if anything. I have been Googling, reading, and trying everything I have found for three days and have had no luck. So I am hoping I can find some help here. I have never seen anything like this. It may be a hardware problem and I'm not smart enough to realise it. But I need to know that too.
System -
Touchsmart 320-1030
Win 7 Home Premium
4 gigs ram
What I have done -
Brought system to my house to see if it will connect, it does not so I am working on it here.
I have rebooted modem & router
Connected systen directly to modem bypassing router
Uninstalled and allowed windows to detect and reinstall network drivers
Updated network drivers
Updated Bios
Tryed to inatall orginal drivers from support but they wont install
I have changed from detect automaticly to use this ip in tcip ip4 and used ip I know is good to my router -
When I did this last thing the wireless did see my network but the network 2 thingy that it makes still won't connect even tho when I search for connections the list says I am connected to my network. The little thing by the clock says not connected. Also the ethernet adapter says unknown public network when I do that. Wireless says unknown public network or connection when I have it detect ip automaticly.
Network discovery will not turn on in homegroup, nether will the services assocated with it.
I have run tweaking . com firewall repair
I have uninstalled avast security, there are no other av or firewall programs
I have uninstalled bonjoir because I read that causes a conflict of somekind
I have run tweaking . com windows repair ( just in case because it looked liked the firewall repair was doing something).
I have run sfc /scannow and it found and fixed some things, ran it again and it found nothing.
I am pulling my hair out with this one. Please help.
Thanks for your time.

The Ultimate Guide to Resolving Profile and Device Manager Issues

The following article also applies to issues after re-setting the severs' hostname. It also applies to situations where re-setting the Code Signing Certifictateas described by Apple has not resolved the issue.
Hello,
I have been plagued with Profile Manager and Device Manager issues since day one.
I would like to share my experience and to suggest a way how to resolve issues such as device cannot be enrolled or Code Signing Certificate not accepted.
I shall try to be as brief as possible, just giving an overview of the steps that resolved my issues. The individual steps have been described elsewhere in this forum. For users who have purchased commercial SSL certs the following may not apply.
In my view many of these issues are caused by missing or faulty certificates. So let us first touch on the very complex matter of certificates.
Certificates come in many flavours such as CA (Certificate Authority), Code Signing Certificate, S/MIME and Server Identification.
(Mountain?) Lion Server creates a so-called Intermediate CA certificate (IntermediateCA_hostname_1") and Server Identification Certificate ("hostname") when it installs first. This is critical for the operation of many server functionalities, including Open Direcory. These certs together with the private/public keys can be found in your Keychain. Profile and Device Manager may need a Code Signing Certificate.
The most straightforward way to resolve the Profile Manaher issues is in my view to reset the server created certicates.
The bad news is that this procedure involves quite a few steps and at least 2 hours of your precious time because it means creating a fresh Direcory Master.
I hope that I have not forgotten to mention an important step. Readers' comments and addenda are welcome.
I shall outline a sensible strategy:
1. Clone your dysfunctional server to an external harddrive (SuperDuper does a reliable job)
2. Start the server fom the clone and shut down ALL services.
3. It may be sensible to set up a root user access.
4. Back-up all user data such as addess book, calendar and other data that you *may* need to set up your server.
5. Open Workgroup Manager and export all user and workgroup accounts to the drive that you using to re-build your server (it may cause problems if you back-up to an external drive).
6. Just in case you may also want to back-up the Profile Manager database and erase user profiles:
In Terminal (this applies to Lion Server - paths may be diferent in Mountain Lion !)
Backup: sudo pg_dump -U _postgres -c device_management > $HOME/device_management.sql
Erase database:
sudo /usr/share/devicemgr/backend/wipeDB.sh
7. Note your Directory (diradmin) password for later if you want to re-use it.
8. Open Open Server Admin and demote OD Master to Standalone Directory.
9. In Terminal delete the old Certificate Authority
sudo rm -R /var/root/Library/Application\ Support/Certificate\ Authority/
This step is crucial because else re-building you OD Master will fail.
9. Go back to Server Admin and promote the Standalone Directory to OD Master. You may want to use the same hostname.
10. When the OD Master is ready click on Overview and check that the LDAP and Keberos Realm reflect your server's hostname.
11. Go back to Workgroup Manager and re-import users and groups.
NOTE: passwords are not being exported. I do not know how to salvage user passwords. (Maybe passwords can be recovered by re-mporting an OD archive - comments welcome! ).
12. Go to Server App and reset passwords and (not to forget) user homefolder locations, in particular if you want to login from a network account!
If the home directory has not been defined you cannot login from a network account.
13. You may now want to restore Profile Manager user profiles in Terminal. Issue the following commands:
sudo serveradmin stop devicemgr
sudo serveradmin start postgres
sudo psql -U _postgres -d device_management -f $HOME/device_management.sql
sudo serveradmin start devicemgr
14. You can now switch back on your services, including Profile Manager.
In Profile Manager you may have to configure Device Management. This creates a correct Code Signng Certicate.
15. Check the certificate settings in Server App -> Hadware -> Settings-> SSL Certificates.
16. Check that Apple Push Notifications are set.(you easily check if they are working later)
17. You may want to re-boot OS Server from the clone now.
18. After re-boot open Server App and check that your server is running well.
19. Delete all profiles in System Preferences -> Profiles.
19. Login to Profile Manager. You should have all users and profiles back. In my experience devices have to be re-enrolled before profiles can be pushed and/or devices be enrolled. You may just as well delete the displayed devices now.
20. Grab one of your (portable) Macs that you want to enrol and go to (yourhostname)/mydevices and install the server's trust profile. The profile's name should read "Trust Profile for...) and underneath in green font "Verified".
21. Re-enrol that device. At this stage keep your finger's crossed and take a deep breath.
22. If the device has been successfully enrolled you may at last want to test if pushing profiles really works. Login to Profile Manager as admin, select the newly enrolled device. Check that Automatic Push is enabled (-> Profile -> General). Create a harmless management profile such as defining the dock's position on the target machine. (Do not forget to click SAVE at the end - this is easily missed here). If all is well Profile Manager will display an active task (sending) and the dock's position on the target will have changed in a few seconds if you are on a LAN (Note: If sending seems to take forever: check on the server machine and/or on your router that the proper ports are open and that incoming data is not intercepted by Little Snitch or similar software).
Note: if you intend to enrol an Apple iPhone you may first need to install the proper Apple Configuration software.
Now enjoy Profile and Device Manager !

Twistan

HI
1. In Action profiles, logon to system and recheck correcion are available in action definition as well in condition configuration and the schedule condition is also maintained. but the display is not coming(i.e in the worklist this action is not getting displayed).

I found the solution, myself, you need to go to network settings and then select manual proxy setting and provide the ip address of the internet server . that's all

Multiple Local Area Connections created at each boot

I have a new Dell laptop with Windows 8.1 - I work from home & connect to the internet via my home wifi network.
The problem I have been experiencing is that my laptop connects to the internet at boot up but then disconnects for several minutes & then re-connects again. This coincides with the Network & Sharing Centre showing a number of Local Area Connections
(numbered 3,4,5,6 etc) being created under Unidentified Public Networks. I have tried disabling the LAC's but they re-enable whenever I re-boot & I have the same issues again. I'd be very grateful for any advice on how to rectify this issue. Thanks.

I send a file from Imac snow leopard OS X 10.6 to the ipadusing bluetooth, but the failure message says the ipad does not have the necessary services. What are these? Do I neeed to have iphoto and ms word to send pix and .doc files?

File Sharing over Bluetooth is not a feature of iOS devices. iOS does not include the required Bluetooth profiles to allow this. You cannot add this feature, so you may as well stop trying.

Enable Local Area Connection in windows server 2008 r2

Hi,
3 Days back i installed the Oracle Virtual box and after installing Ubuntu in it, when i changed the network mode from NAT to bridge, i lost the connectivity with server.
The data center guys has provided a channel in which we can access the server command prompt.
Using this i have removed the following entries from the registry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VBoxDrv
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VBoxNetAdp
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VBoxNetFlt
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VBoxNetUSBMon
but now issue is my network card "Local Area Connection" is not getting enabled and i cant access my server.
How can i enable my Local Area Connection back.
Thanks

Hi
Netsh can do this for you:
netsh interface set interface name="Local Area Connection" admin=enabled
Replace "local area connection" with your connection name.

Imaqdx multiple cameras show as Local Area Connections in System tray, but only one shows up in MAX.

I have two GigE cameras (Pulnix 4200GE) in my system, each having it's own NI GigE Vision Adapter. The adapters show up in Network Connections and in the system tray as "Local Area Connection" (LAC) and "Local Area Connection 2" (LAC2). However, I can only see one camera at a time in MAX. If I start with both adapters disabled, then enable LAC followed by LAC2, I see one camera (cam0), then both (cam1 shows up) but about 6 seconds later the second camera (cam1) disappears! If I enable the adapters in the reverse order (LAC2 followed by LAC), only cam0 shows up. I can see each camera alone by disabling the other adapter but I cannot get them both to stick around.
There is also an anomoly in the MAX display of the cameras. If I right-click the camera in the NI-IMAQdx folder the context menu has a 'Camera->' sub-menu which shows both cameras even if one has had its adapter disabled. And regardless of which camera I see (cam0 or cam1) the list shows the same camera is checked. This is in conflict with the data showed in the Camera Information tab of the attributes pane in MAX, which shows a different camera (ID'd from the serial number) based upon which one shows up in the folder list. And changing the selection check-marked in the 'Camera->' sub-menu has no effect on the information displayed in the attributes pane.
I have followed the troubleshooting guide and they are both DHCP-enabled and have Auto private addressing enabled. I have updated the Adapter drivers. This is a NI PXI system running Win XP.
Thanks in advance for any help!
Jesse

If you are running Windows XP you need to go to the network settings tab in Windows and bridge the two "NI Gige Vision Adapter" ports together (select both, right click and select option to bridge network adapters). This is due to a deficiency in Windows XP where multiple adapters within the same logical subnet (the link local address space, in this case) are not able to be used independently for broadcast traffic. This workaround is not needed on Windows Vista or later.
The details you are seeing by right-clicking the camera in MAX is the list of camera files (saved settings) that can be associated with the camera. You probably have two because both were visible at one point or another to IMAQdx and so unique ones were created. They are probably both associated with the same camera file because if they are both the same model name we have some logic that assumes that if one is removed and a new one is attached, to use the previous camera file. This only happens in certain circumstances---normally if you start with one camera and add a second (or start with two) they will both get unique files created to store their settings. In your case you can use MAX to set the correct association as needed.

How to change the properties of the local area connection

Try to make change in the properties of the local area connection, i.e. click Start --> Control panel --> Network Connection --> Local Area Connection --> properties. Then select Internet Protocal(TCP/IP), click on the Properties. Normally, the PC is set at Obtain an IP address automatically. Now need to change to Use the following IP address, then enter the IP address, Default gateway address. after that, click OK.
I am wondering, is Labview could do the setup as described? Once all done, is it possible to change the TCP/IP setting back to "Obtain an IP address automatically"?
Thanks,
Test

Thanks smercurio_fc.
I tried but not working. The way I try to do is connnecting two PCs directly through Ethernet cable. Then change the IP addresses as mentioned, after that ping another PC. If done manully, working.
After run the program you mentioned in your email, I check the "ipconfig /all" in the DOS window, it is still the old IP address. If changed manually, check ipconfig in the DOS window, it is changed.
Any thoughts?
Thanks,
