We are experiencing unknown DNS? issues affecting only XP machines on our network. Name lookups from the command prompt succeed despite the fact that web browsers and pings are failing when hostnames are specified. The issue often resolves itself within a 5-30 minutes but will remerge later without any visible pattern/reason.
Our 2000 and 98 machines are fine. These problem began a week ago here though contact with other admins in our (school) network show a few people have been experiencing this problem for months.
Any ideas or recent malware affecting DNS in XP boxes only?
