Cannot communicate with primary DNS server?

Tashiie · 06-07-2009, 06:33 AM

Hello. My dad recently upgraded his laptop from XP to Vista. His vista box can connect to his office's modem router; but at home it's a completely different story.

When I plug in the ethernet cable, it shows that it's connected but websites will not open in internet explorer or firefox.

When i try to diagnose the problem, the error message "Cannot communicate with primary DNS Server (172.40.7.220)" pops out with the option to reset the network adapter "Local Area Connection". But when I click the option to reset, the same error message pops out again.

My Internet Protocal is already set to "Obtain DNS Server address autmotically" and I have no idea what else to do.

Can anyone please help me? ):

hi

Did you try: RUN>cmd (as administrator) >ipconfig /flushdns

You can also try:Start>Run>cmd (as administrator) and reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Also reset TCP/IP stack to installation defaults: netsh int ip reset reset.log

You have to reboot your system for the changes to apply.

^^

Those commands are for XP. Here are the ones for Vista

Windows Vista
Open up a command prompt (Start > All Programs >Accessories > alternate click on Command Prompt > select "Run as Administrator"
Type the bolded commands into the command prompt window:

Reset WINSOCK entries: netsh winsock reset catalog
Reset IPv4 TCP/IP: netsh int ipv4 reset reset.log
Reset IPv6 TCP/IP stack: netsh int ipv6 reset reset.log

When finished reboot

It still doesn't work D:

The same error messages pop out. And the connection still shows "Local Only" ><. I'm using a D-Link router.

Any other suggestions? :[.

Is his computer part of a domain? You may have to make it part of a workgroup for it to work. Also, did this work in both locations before it was upgraded?
