Tip & How-To about Computers & Internet

IP address 0.0.0.0

First of all, disable and re-enable the connection. When you change the IP address from automatic to a fixed IP address while the adapter is not connected, you always get a 0.0.0.0 address at first when the adapter reconnects. If this doesn't solve the problem, read on.
Symptoms:

  • You cannot obtain an IP address from the DHCP server. The IP address is 0.0.0.0.
  • The DHCP service is not running, although it is set to Start Automatic.
  • When you try to start the DHCP service, you get the error message: Could not start the DHCP Client Service on Local Computer. Error 1075: The dependency service does not exist or has been marked for deletion.
This problem can occur after uninstalling Norton AntiVirus, which sets the DHCP service as depending on itself. It can also occur when the computer name of the client computer is too long. Make sure that all computer names in your network are no longer than 15 characters.
First set a restore point, so you can undo your changes, should anything go wrong (Programs, Accessories, System programs, System restore).
After setting the restore point, to remove this dependency, do this:
  • Click: Start
  • Click: Run...
  • Type: regedit
  • Click: OK
  • Navigate to the following keys in the registry:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DHCP
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NetBT
  • For each of these, on the right side, double-click: DependOnService
  • Delete any lines containing either SYMTDI or NISDRV.
  • Click: OK
  • Close the Registry Editor.
  • Reboot.

My laptop cannot automatically pick up an IP address


Don't send it away.
To automatically get an IP addressed assign you must have the network adapter set to "Obtain an IP address automatically"
Check it from a command prompt
click on start | run| type in cmd to open a command window
type ipconfig /all in the command window and see if Autoconfiguration Enabled . . . . : Yes is in the list of information, if not follow the guide below to change it.

DNS service and DHCP service are not normally run on a person's computer, these are services that run on remote internet servers, local network servers or router/wireless access points, to name a few examples.
You need to verify that your network adapter's TCP/IP settings are set to automatically obtain an IP address.
Go to network connections and open the window.
Find your network adapter and right click once on it and select "PROPERTIES" at the bottom of the context menu list that appears.
Usually this will be labeled something like Local Area Connection.
Right click on it and select properties.
In the window that open you'll see several items with checkboxes, find the one labeled
Internet Protocol (TCP/IP), click once on it to select it and then click on the button "PROPERTIES"
Look and see if the bullet choice "obtain an IP address automatically is bulleted, if not click in the circle to enable the bullet.
While in that properties sheet, make sure that the item Obtain DNS server address automatically is also bulleted (selected)
Click OK, OK
click on START | RUN and type in the box cmd to open a command window
in the black command window type the command
ipconfig /all
you should see an IP address, subnet mask and default gateway along with lots of other IP info
see if you've got an IP address in the list. If not type the following in the command window

ipconfig /release
this will force the IP to release any address it is holding
then type
ipconfig /renew

this will force a renew of the address

C:\Documents and Settings\tolm4454>ipconfig /all

wireless router


My suggestion would be to first disable any encryption on the router to make your wireless network simple first to try and troubleshoot these problems. check if any MAC or IP Address filters are active on the wireless router, you can either enter the IP address of the slingbox wireless adapter or its MAC address if you HAVE enable filtering, but again, try diagnosing without filtering or encryption enabled. Also ensure your slingbox wireless adapter has its settings set to 'automatically assign IP address (enable DHCP)' so it gets its address automatically.
