Hi,

Setup - Main Pc connected to internet, with firewall etc
Other PC's using ICS to access internet.

Until recently (yesterday) all worked fine.

Problem. Can surf from main PC but rest cannot. Specific sites can be
accessed by other pc's. Can ping sites from other pc's but webpages fail.

No evidence of viruses etc.......

Any ideas?
