Can you explain what that does?

Not keen on rebooting right at the moment as I'm in the middle of something so will come back to that.

no hurry for this, do it when convenient

1.2 - What’s the difference between Winsock and TCP/IP?

Networks are made of several layers. Network people talk about those layers in terms of the OSI network model.

TCP/IP is a network protocol, meaning that it is at layers 3 through 4 in the OSI model. A network protocol provides services like addressing, data transport, routing, and logical connections across a network. Two computers must use the same network protocol if programs running on those computers are to communicate. Other common network protocols include Novell’s IPX, 3Com/IBM/Microsoft’s NetBIOS and Apple’s AppleTalk. TCP/IP is the most popular network protocol today: virtually all computers support it.

Winsock is an API that lets a Windows program send data over any network transport protocol. There are several functions in Winsock that only work with TCP/IP (e.g. gethostbyaddr()), but there are newer generic versions of all these in Winsock 2 which allow you to use other transports.

Most of the Internet connectivity problems arise out of corrupt Winsock settings. Windows sockets settings may get corrupted due to the installation of a networking software, or perhaps due to Malware infestation. You will be able connect to the Internet, but the packets won't transfer back and forth. And errors such as Page cannot be displayed may occur when using Internet Explorer.


the command is effectively flushing the winsock caches in case they (and sometimes they do) get bunged up.

Thanks. That sounds like it will be worth trying.

if I'm having to flush the DNS, I always do this as well, just to cover most of the bases
