My Windows 7/64 machine has suddenly started to act funny. Everything will be running fine, when suddenly most network access methods will fail. These things continue to work:
- Accessing network mapped drives
- Ping (both intranet and internet)
- DNS for URL resolution
These things fail:
- Printing to a local network device
- HTTP (I cannot browse to Internet sites, nor my local router's internal http server)
I've tried using ipconfig /release then /renew without success. Rebooting the machine cures the problem, until it happens again (anywhere from 4 to 40 hours later).
Any thoughts or suggestions?
