Solved Limited connectivity, DHCP Client not starting

[vaiolady]

Hi.
I used to be able to connect to the internet before with no problems. 2 wks ago, the Wireless connection started showing "LIMITED CONNECTIVITY", though, it can see all the wifi networks available in the area. Other computers and wifi enabled devices can all connect easily to the same network. I've tried the following solutions(from the forums) already:
-re-installing drivers, disabling-enabling network adapters
-made sure the passwords are correct
-disabling firewalls
-turning on-off (5mins) the router +PC
-removing and reloading the network
-scanned software/hardware for problems thru built in "vaio care"
(indicated that everything is running normally)

I also tried to run the Network Diagnostics but this error msg always appear= "The Diagnostics Policy Service is not running."- even if i run it as an administrator..

Checked the Local Services and found out that DHCP Client is not running- Tried starting it several times but it won't start and this error msg always appear "Windows could not start the DHCP CLient service on local Comp. Error 5: Access is denied."

I'd appreciate any help/assistance/idea from anyone. Been trying to sort this one out for 4 days now, and still found no solution. Thanks for taking time in reading this.

PC details: SonyVaio E-series, Intel i5, Windows 7 HomePremium (64-bit)

Welcome to SF,

Have tried a System Restore? Restore it to a point where you were able to wireless connect.

Verify that all your Network Services are Started from Control Panel and its Dependencies.
Click on start and type services.msc press enter.
• COM+ Event System (for WZC issues)
• Computer Browser
• DHCP Client
• DNS Client
• Network Connections
• Network Location Awareness
• Remote Procedure Call (RPC)
• Server
• TCP/IP Netbios helper
• WLAN AutoConfig
• Workstation

Thanks for replying.. =)

I've tried restoring several times but still the problem persist.

I was able to start all of the services above except for "DHCP Client".
This msg always appears: "Windows could not start the DHCP Client service on this comp, Error 5: Access is denied."

Any idea why? Honestly, I don't have extensive knowledge on PCs.....I just kept trying
All the possible solutions posted here. I've tried turning off firewalls as well..

Have you checked the dependencies tab also?
You might want to do sfc /scannow:

[vaiolady]

Yes, I have checked the dependencies and they are all started.
Ran the scannow several times as well and rebooted the machine after each scan. It says that it finds no error.
Still same limited connectivity. Dhcp Client still won't start in the services.

That's a good catch 2xg! On my system, the DHCP client lists three system drivers as dependencies. They are:

• Ancillary Function Driver for Winsock
• NetIO Legacy TDI Support Driver (itself dependent on TCP/IP Protocol Driver)
• Network Store Interface Service (itself dependent on NSI Proxy Service Driver)

With the exception of Network Store Interface Service, which as the name says is another service, all of these drivers are found in Device Manager under Non-Plug and Play Drivers. (You need to enable hidden devices to see these entries.)

So it's time to see if one of these drivers, or the service, are either disabled or missing.

I've only disabled the DHCP SERVER in the router & gave manual address' s in NIC properties
with correct subnet mask. default getway & DNS should have your router address.
that solved the problem

Thanks for letting us know.
Actually, you don't have to disable the DHCP Server in your router, you may always assign Manual or Static IP in your LAN or WLAN setting, just an FYI....

The manual address's have been before.
Only when i disabled dhcp server, the "limited or no connectivity" disapeared

First back up your registry Back up the registry
Now see if this might work ....

To use Registry editor to resolve this problem, follow these steps:

1. On the upgraded Windows Server-based , click Start, click Run, type regedit in the Open box, and then click OK.

2. Locate and then right-click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dhcp

3. R/Click and select Permissions, click Add, type network service, and then click OK .

4. Click to select the Full Control check box in the Allow column of the Permissions for NETWORK SERVICE box, and then click OK (Repeat for all subkeys).

5. Locate and then right-click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip

6. R/Click and select Permissions, click Add, type network service, and then click OK.

7. Click to select the Full Control check box in the Allow column of the Permissions for NETWORK SERVICE box, and then click OK (Repeat for all subkeys)

I know this is an old thread, but the original poster has the exact same issue as I am experiencing. I am desperate to find out how to fix the issue for my laptop.

I second to above comment. Thanks for the post, the key is to make sure all the permission is inherited to all the subkeys. It wasted me quick a bit of time finally get there. I read the original post about setting the Permissions.

I still have the problem not able to start the Diagnostics Policy Service! Same access denied problem!! One thing at a time. My machine was working fine and all the sudden, problem appear and couldn't do System Restore either.

solved but needed extra steps

I was facing same problem. Even after following all the above steps still I was not able to connect to internet.

After giving administrator rights to "Local service" and "Network service" now the problem is resolved at my end.

Hi All

As for one of the previous messages, the dhcp client and tcpip service need to start loged on as Local Service, so the permission need to be set up correctly. I found on different PC that these services have read permissions for "Network Service" and "Local Service" in registry. After applying pemissions however the DHCP client still screamed "Access denied" so I had to setup full access to them for "Network Service" and "Local Service". I found it painful to apply all of these to every sub-key. But you using "subinacl.exe" command makes it easy. You need to run these commands:

subinacl.exe /subkeyreg "HKEY_LOCAL_MACHINE\system\CurrentControlSet\services\dhcp" /grant="Local Service"

subinacl.exe /subkeyreg "HKEY_LOCAL_MACHINE\system\CurrentControlSet\services\tcpip" /grant="Local Service"

subinacl.exe /subkeyreg "HKEY_LOCAL_MACHINE\system\CurrentControlSet\services\dhcp" /grant="Network Service"

and

subinacl.exe /subkeyreg "HKEY_LOCAL_MACHINE\system\CurrentControlSet\services\dhcp" /grant="Network Service"

You can get subinacl.exe here:

Download SubInACL (SubInACL.exe) from Official Microsoft Download Center

It is Microsoft piece of software.

Good luck

Same problem solved.

For my problem, I'm on Windows 10 btw, the DHCP Client would not run, giving me an error 1079 about dependencies not running. To fix this issue, go to services, find DHCP Client, right-click on it and click on properties. Then once the dialogue box opens, go to Log On box at the top, and click on This Account. For the username type NT Authority\LocalService. Just like that type it in, and leave the password boxes blank, then click apply and ok. After doing so my computer connected to the internet. If you have any other important services not running repeat these steps for all non-running services if they will not start on their own.
