Primary DNS Server

[dla_kemper]

Hello all,
I hope someone can end this stress that Vista has given me. I work at a huge hospital that has local wifi access for our patients, and inbetween patient care I like to work on my homework with my online courses. My friend was able to log her Windows XP laptop onto the network just fine, however when I connect it connects to the actual network, but doesn't connect from the network to the internet. (DavidLaptop-UMHGuest2-X-Internet)

I get the error message 'Cannot communicate with Primary DNS Server (192.168.11.1).' I know that even when I was traveling last summer my new laptop wouldn't connect to the hotels wifi which really ticked me off, now I think it may be perhaps settings and I'm not very good at messing with them.

I am begging please someone help, even my tech support isn't able to provide me with Vista help.

That's a very screwball IPCONFIG result.


Configure DHCP for Windows Vista.

1. Click on the Start menu, and select Control Panel.
2. Click on Network and Internet. (Skip this step if you do not see this Control Panel item.)
3. Click on Network and Sharing Center.
4. Click on Manage network connections.
5. Right click on Local Area Connection and choose Properties. If Windows say it needs your permission to continue, click Continue.
6. Select Internet Protocol Version 4(TCP/IPv4) and click Properties.
7. Select Obtain an IP address automatically.
8. Select Obtain DNS server address automatically.
9. Click OK to close the TCP/IP Properties window.
10. Click OK to close the Local Area Connection Properties window.
11. Click Close to close the Network Connections window.
12. Click Close to close the Control Panel window.
13. Restart your computer.

Post another IPCONFIG /ALL after the reboot.

I think maybe Vista is the issue here.


Changes that may help to increase the compatibility of Vista with older networking devices:



Disable the IP Helper service:

1. Hold the Windows key and type R, enter "services.msc" (without the quotes) and press Enter
2. Scroll down to the IP Helper service, right click on it and select Properties
3. In the dropdown box that says "Automatic" or "Manual", set it to Disabled and then click on "Apply"
4. Then click on "Stop" to stop the service from running in the current session
5. Click OK to exit the dialog



Disable IPv6:

1. Hold the Windows key and type R, enter "ncpa.cpl" (without the quotes) and press Enter
2. Right click on each network connection and select "Properties"
3. Remove the checkmark from the box next to "Internet Protocol Version 6 (TCP/IPv6)
4. Click OK to exit the dialog

NOTE: You should do this for each network connection.



Disable the DHCP Broadcast Flag:

Link: http://support.microsoft.com/default.aspx/kb/928233

1. Hold the Windows key and type R, enter regedit and press Enter.
2. Locate and then click the following registry subkey:
3. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
4. In this registry path, click the (GUID) subkey to be updated.
5. If the key DhcpConnForceBroadcastFlag does not exist, use the Edit menu, point to New, and then click DWORD (32-bit) Value. In the New Value #1 box, type DhcpConnForceBroadcastFlag, and then press ENTER. If the key exists, skip this step.
6. Right-click DhcpConnForceBroadcastFlag, and then click Modify.
7. In the Value data box, type 0, and then click OK.
8. Close Registry Editor.

NOTE: You should do this for each and every GUID subkey.
NOTE2: (GUID) is a mnemonic for the individual subkeys, the actual text "GUID" does not appaer.




The only program I'm aware of that currently relies on IPv6 is the new Windows Meeting Space. The first 2 changes will cause that program not to work - but will leave all of your normal (IPv4) connections unaffected. If it causes problems that you can't overcome, simply revert back to the original settings.
