Windows 7: Can you "refresh" your LAN?

Here are commands to refresh your LAN connection. Use these in the command prompt (doesn't need to be elevated):

- ipconfig /release - will release your internet connection

- ipconfig /renew - will refresh your internet connection by reacquiring an IP address from your router. You don't need to run ipconfig /release before using this command.

- flushdns - will reacquire DNS information

So if I wait 15m the network may refresh by itself?
Thanks
my bad - seems to be 12 mins as per Description of the Microsoft Computer Browser Service

Yes that does work, as does resetting the router, but rebooting is then the faster choice, plus you can refill your coffee while you do it!
I'm just checking to see if I'm missing something obvious and simple.

of course, for a small home network, one can just 'cheat' by having static IP's and stuffing the host ip mapping in the hosts file.

ps: guessing the network folder uses browser adverts and broadcasts (think 15 mins used to be the old number for cache updates and refreshes)
Most routers have DNS servers in them, these days.

My solution to the problem was to simply make my own network shortcuts right in my home folder... One for each computer. The shortcuts have the added advantage that clicking them will actually wake the computer from standby...

It's been 20 min and XP still has not shown up. But the D-Link Media Server on XP does, and right away.

That sounds like a practical solution. I'll give it a go.

Windows 7 Ult, Windows 8.1 Pro,
 
 

This is a typical problem which is easily fixed.

Solution is really easy just modify one key in registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
create or modify 32-bit DWORD: LocalAccountTokenFilterPolicy
set the value to: 1

The link below shows you how it works and will answer any other questions you might have.

Hey Chev - Thanks for the reply.

I've just finished reading some stuff about LocalAccountTokenFilterPolicy and it seems that what this does is disable the UAC Remote Restrictions, allowing unlimited network access to administrative shares.

Do you think that this fix creates a potential security vulnerability?

One thing to check with the XP machines is that they are running SP3 - there are some additional components included to allow the later OS to poll the XP machines using the new networking methods (link Layer topology)

It is still available as a separate download for non SP3 systems

Download details: Link Layer Topology Discovery (LLTD) Responder (KB922120)
