I'm experiencing what appears to be a dns lookup problem after my laptop sits
unused overnight. The next morning when I attempt to access a web site
(either with IE or Firefox), I get a "site not found" error.
I've tried ipconfig /flushdns and ipconfig /registerdns. Neither solves the
problem. nslookup will resolve the name. Using the ip address from
nslookup directly in IE or Firefox will display the web page. So I know
basic connectivity is working.
The only action that solves the problem is to reboot the laptop. Logging
off and then logging in again does not help.
I have searched many different groups and discovered several people
reporting what appears to be the same problem. However, I have not been able
to find a solution.
Any suggestions?
Details:
XP Pro SP2 - configured to use DHCP. No explicit DNS entries or
Gateways defined for network connection. ipconfig /all shows that DNS
Servers and Default Gateway point to wireless router. IP Address is valid
and lease is current.
Wireless router - acts as DHCP server for internal network. Config page
for router shows that DNS Servers and Default Gateway point to ISP supplied
values. IP address assigned by ISP is valid and lease is current.
