Ping works, DNS doesnt, some users only
Would very much appreciate any suggestions on where to go next with this problem:
Windows XP machine connected via USB Cable Modem to UK NTL broadband network. NIS 2002 firewall. This is a configuration which worked fine until recently.
However, since installing MS Office 2003, Internet access has stopped working for some users - specifically, those that have used Office.
It's very strange:
- ipconfig /all reports all the usual things fine, including the addresses of two DNS servers that work fine on other machines
- I can ping IP addresses by number, including the DNS servers
- However, any DNS request, such as pinging a domain name, or nslookup reports a failure. nslookup, for example, responds:
*** Cannot find server name for address 194.168.4.100
*** No response from server
*** Cannot find server name for address 194.168.8.100
*** Default servers are not available
Default server unknown
Address 194.168.4.100
If I log out and log in as a different user (one that has not used Office 2003), then everything works fine.
My thinking is:
- since I can ping IP addresses, it's not a hardware problem
- since it works on other users, it must be something specific to some user -- perhaps some Registry key under HKEY_LOCAL_USER?
However, where to start looking?
Any suggestions much appreciated.
