I've been using the hosts file to for local website development, and it's recently stopped working. No entries other than localhost resolve.
I've simplified to test, so it now contains only
127.0.0.1 localhost
::1 localhost
127.0.0.1 test.dev
localhost responds to ping, test.dev does not.
The file is called hosts with no extension
It has no trailing spaces
It's saved in C:\WINDOWS\System32\drivers\etc which matches the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DataBasePath
Oddly, despite UAC being on, I can edit, delete and save the file without admin permissions
No proxy is being used, PC is not connected to network for testing
Stopping the DNS Client service seemed to resolve the issue for a few minutes, test.dev briefly resolved but doesn't any more.
Only firewall is Windows'
Machine has been restarted.
Is there anything else I should try?
