windows version: Server 2003 R2 Standard x64 SP2
Verify it’s not working
ipconfig /displaydns | more
Check for type-o’s!
Start with the simple solution first
Verify hosts file location
Open Registry Editor
Verify key: My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services|Tcpip\Parameters\DataBasePath
Copy Value data and paste it into Explorer to verify you are editing the correct file
Verify file permissions (This was my issue)
If machine\users is not given Read and Read & Execute permissions, add the account.
