Hello.

The following is Windows '9x specific:

Unless a DNS server is used, the name defaults to the same as the LAN
manager name. If a DNS server is used, then a name is provided in the
networking control panel. This gets stored in the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP

libsocket uses the Regdos Group's registry code to get this value. I think
this key will only be created by Microsoft TCP/IP stacks. No communication
with Winsock is necessary. If DHCP is being used, then it gets a bit more
complicated. I've documented where the host name, etc., is found here:

BTW the user name gets stored in:

HKEY_LOCAL_MACHINE\Network\Logon

I think I can cope with it ;)
