top disc Hello All Some time back I had my external interface as 10.0.0.1 and my internal as 192.x.x.x I then changed my external IP to a public IP address. The registry key below still refers to my old IP addresses and in fact some software still binds to this old IP. Can someone explain the use of this key? HKEY_USERS\S-1-5-21-823518204-492894223-1060284298-500\Software\Microsof t\Windows Media\WMSDK\Local\AutoProxyCache\LAN\DetectedInterfaceIps Is it an ISA key? An I change it? Any help appreciated. William
