teleman :
I have one pc on my network that can't access the internet. I can ping the machine and log-in via remote desktop. PC can't ping the dns server. The ping reaches the gateway. Nslookup can't find server, request times out. Any ideas?
Is there any firewall rule preventing that particular host from passing a dns request through the firewall
Where is the DNS server, same LAN or is it using an outside server?
Is this a workgroup or domain?
Is that worksation using dhcp?
If not have you confirmed any static DNS settings?
Does it have a misconfigured software Fire Wall blocking port 53?
Have you checked the host file to make sure it hasn't been tampered with?
do an ipconfig /displaydns to see what, if anything is in the dns cache and then do a ipconfig /flushdns
can you ping that workstations FQDN from another workstation?
