Firebird tip From the FAQ
On Windows XP (SP2), when I disconnect the network cable, my local programs are unable to connect to the local loopback server (127.0.0.1 Localhost). Is there something I have to set in the Firebird configuration?
No, it’s a “feature” of WinXP called DHCP Media Sense, that automatically disables the TCP/IP stack whenever there is no network connection. Switching it off requires adding a key to the Windows Registry. Open the Registry Editor and locate the folder HKEY_LOCAL_MACHINESystemCurrentControlSetServicesTcpipParameters. Add a new DWORD key named DisableDHCPMediaSense with a value of 1. To re-enable Media Sense, change the value to 0.
