Vista - Vista to XP lan games problem: THE SOLUTION

The Vista to XP Lan Games connection problems Solution!!

After trying to play several different lan games with my Vista equipped
machine and not being able to join I finally found the way to make it
work!! OH JOY! SO many forums browsed in vain. Finally I found it. For
all of you, the problem was ipV6.

To fix that problem you need to disable ipv6:

1- Open the Network and Sharing Center in the Control Panel on the
Vista equipped machine

2- Click on the little blue letters "View Status" next to your LAN
connection (my wireless connection for me)

3- Then click on the Properties button (not wireless properties or
anything else, just properties)

4- Click continue on the little annoying pop-up vista window if any

5- Now look for the field under "this connection uses the following
items" there with Client for Microsoft Networks/QoS Packet Scheduler
etc. You should find many of those with little checkboxes next to
them.

6- Now i'm not very sure if it's only ipV6 that you need to disable, so
to make sure, do steps 1-5 with you XP equipped machine to check what
they have in that field, and keep the checkboxes checked for only those
items. Uncheck everything else. I uncheked Internet Protocol Version 6
(TCP/IPv6) , and the two Link-Layer ones.

7- Try again to join your lan game it should work fine ( it did for me
and our Dungeon Siege 2 Lan Party!)

Hail! to the Grand Superlapin that saves us all!!!!

I tried your advice and unticked all the options except the estential
IPV4 TCP/IP, Microsoft Client and QoS protocols.

Still even with these unselected and the firewalls turned off on both
the XP and Vista Machines I was unable to connect a Lan game for Age of
Empires II and Dawn of War.

I did get Age of Empires II to work by plugging in a RS232 serial
crossover cable in between the two machines serial ports and using the
serial game option.

I have also had to change my router hardware to a single unit from
having a wireless router connected to a VoIP router then to the gateway
router. This worked perfectly with XP, Win 2k and Linux boxes on my
network. But the Vista Box on standard settings would not connect to
the Internet, unless I plugged it directly into the gateway router.

To get over the problem I to turned off IPV6 and the Web pages started
to work. But the POP protocol did not and I could not download email.
So I purchased a all-in-one VoIP/Wireless/DSL router and it worked.

after many hours also facing this problem I also too could not get LAN
gaming to work - I eventually fixed by a simple upgrade to the firmware
on my US Robotics DSL router, more snooping around regarding this
problem reveals it may also exist with older linksys DSL routers......

the problem I believe (guessing here) is the older firmware may block
high value port numbers or is simply unable to support them.

my symptoms were typical of many other emails reporting this problem -
WAN access was fine, pinging between machines works all firewalls/ virus
things switched off.

Anyway hope this helps others.
