XP machine can't see Vista machine on wireless network

I have set the same workgroup name on both computers and set both to allow
file sharing (and shared at least 1 folder). The Vista machine has no
trouble accessing the XP machine, but the XP machine can't see the Vista one.
I tried dl'ing the hotfix for that problem, but was told that I didn't need
the update. When I click on "View workgroup computers" on the XP machine I
get a pop-up error that says "Workgroup is not accessible. You might not
have permission to use this network resource. Contact the administrator of
this server to find out if you have access permissions. The network path was
not found."

Probably a misconfigured firewall and/or you forgot to create matching user
accounts/passwords. See below for general troubleshooting.

Here are general network troubleshooting steps. Not everything may be
applicable to your situation, so just take the bits that are. It may look
daunting, but if you follow the steps at the links and suggestions below
systematically and calmly, you will have no difficulty in setting up your
sharing.

Excellent, thorough, yet easy to understand article about File/Printer
Sharing in Vista. Includes details about sharing printers as well as files
and folders:

For XP, start by running the Network Setup Wizard on all machines (see
caveat in Item A below).

Problems sharing files between computers on a network are generally caused
by 1) a misconfigured firewall or overlooked firewall (including a stateful
firewall in a VPN); or 2) inadvertently running two firewalls such as the
built-in Windows Firewall and a third-party firewall; and/or 3) not having
identical user accounts and passwords on all Workgroup machines; 4) trying
to create shares where the operating system does not permit it.

A. Configure firewalls on all machines to allow the Local Area Network (LAN)
traffic as trusted. With Windows Firewall, this means allowing File/Printer
Sharing on the Exceptions tab. Normally running the Network Setup Wizard on
XP will take care of this for those machines.The only "gotcha" is that this
will turn on the XPSP2 Windows Firewall. If you aren't running a
third-party firewall or have an antivirus/security program with its own
firewall component, then you're fine. With third-party firewalls, I
usually configure the LAN allowance with an IP range. Ex. would be
192.168.1.0-192.168.1.254. Obviously you would substitute your correct
subnet. Refer to any third party security program's Help or user forums for
how to properly configure its firewall. Do not run more than one firewall.
DO NOT TURN OFF FIREWALLS; CONFIGURE THEM CORRECTLY.

B. For ease of organization, put all computers in the same Workgroup. This
is done from the System applet in Control Panel, Computer Name tab.

C. Create matching user accounts and passwords on all machines. You do not
need to be logged into the same account on all machines and the passwords
assigned to each user account can be different; the accounts/passwords just
need to exist and match on all machines. DO NOT NEGLECT TO CREATE
PASSWORDS, EVEN IF ONLY SIMPLE ONES. If you wish a machine to boot directly
to the Desktop (into one particular user's account) for convenience, you
can do this. The instructions at this link work for both XP and Vista:

Configure Windows to Automatically Login (MVP Ramesh) -
http://windowsxp.mvps.org/Autologon.htm

D. If one or more of the computers is XP Pro or Media Center, turn off
Simple File Sharing (Folder Options>View tab).

E. Create shares as desired. XP Home does not permit sharing of users' home
directories or Program Files, but you can share folders inside those
directories. A better choice is to simply use the Shared Documents folder.
See the first link above for details about Vista sharing.
