Can anyone suggest an explanation for this?

I have a small network: 1 desktop and 3 notebooks. I recently wiped one of the notebooks and have reinstalled XP on it. Now, if it is connected to the other machines via cable it can see and access them all. If I try and use its wireless connection I still get internet access but can't access one of the other notebooks, but can the desktop and other notebook.

I'm baffled.

Does the notebook that doesn't work have specific user account security set
up for the shared resources ?  If so, then the user security information may
have changed on the wiped notebook, and you may need to re-setup the share
security on the target notebook.

Not as far as I'm aware, but who knows what MS do. I set up all my machines with the same user name (me) and password. My wife's is different - it user her name Smiley

But even if your guess were right why when a bit of wire is used does it work and when no wire it doesn't? I also forgot to add I can go the other way Vista -> XP regardless of wired or wireless.

Silly question but I assume they're getting the same IP in both cases of
wired and wireless (i.e. from same router on same subnet ...).

You did not specify what type of access you're trying to achieve but I
assume file and printer sharing.

First thing to check is if you can ping the inaccessible machine while on
wireless - meaning that you have IP level communication and have problems
further up the stack.

If ping is OK then do you use AV/firewall software that might differentiate
between wireless/wired ?

It sounds like your other machine is Vista (which can be evil for sharing)
but one thing to try is to setup the network connection type on that one as
"Work network" - if you use Home then Vista tries to use IPv6 while work I
found tends to work lot better in regular IPv4 intranetworking scenarios.

Good idea. I'll see

Not as far as I know

Good guess, and a very interesting observation. I'll have a go

The final thing I forgot to ask is how exactly are you are accessing the
other PC - by name or by IP.

If ping works but you can't access the share still and are using name then
it might be worthwhile to try accessing it using IP  as in "\\<ip>\<share
name>" (e.g. \\1.2.3.4\myfiles).

It'll be the weekend at the earliest before I get a chance to mess about. The good news is that replacing the Vista m/c with an XP m/c seems to have improved the whole networking performance. I do wish I'd bought the XP upgrade with my main Vista notebook Smiley

I agree with Raul's suggestion, ie, to setup the share with an IP instead of
the name (assuming you're not using DHCP). This was an issue (and solution)
when mixing Win2000 and XP in our network.

If that works it is my (imperfect) understanding that it means the
problem probably lies in Windows Name serving because IP addressing
bypasses WINS .. or something like that.  Smiley

But if it all works on cable I think it most likely that the other
laptop not playing ball can see a difference in the rebuilt machine
and does not trust it.
