Ok so i don't really think it is a dns issue, but i can't work out what it is... so here comes the information...
My setup: Laptop wirelessly connected to Linksys WRT54G via 3com CMX to ntl BB. Laptop 128mb ram, pentium 998, win2k, fully patched, AV/ spyware free.
My problem: at completely random intervals i will get pcbd/ cannot find server on every site that i try.
The solution: Logging onto the router config page, clicking dhcp renew, then refreshing the page.
What i have ruled out...
- I am not going through a proxy, even if i specify one it doesn't make a difference
- I have tried using non-ntl dns
- I have tried 3 different firmware versions for the router
- Connecting wired to the router doesn't make any difference
- When the connection drops i can browse by ip
- nslookups work fine all of the times
- pings/ traceroutes etc are showing no problems
- I get the same problem whether i use IE6 or firefox
The strange parts...
- It sounds like a router issue, but none of the other computers on the network have the same problem
- I don't think it is a network issue, because i had the same problem when connected to ADSL at Ann's house
- So it makes it seem like a pc issue... but.... I get the same problem when running in safe mode with networking and there are no processes running that would cause the problem.
Any ideas would be appreciated!!

EDIT: forgot to mention that my combined AV/firewall/adblocking/ spyware application has been ruled out as well
