My Vista home premium computer cannot access the shared folders on my XP home computer via my LAN.

I can access the Vista computer from the XP, but when I try to open the XP folder from Vista, I'm prompted for user name and password. Both computers are in the same workgroup, I have the same logon user name and password on both as well.

If I try to connect with net use, I get:
system error 86
the specified network password is not correct

Firewalls are off
Anti-virus is off
The RestrictAnonymous registry setting is 0

Welcome, hanick.

Sounds like you've done your homework, and perhaps have covered everything we know how to fix. My first post here was a similar problem and I eventually "fixed" it by reinstalling.

Just to confirm, the OS is XP Home (not Pro or Media Center), right? Please show for the XP ...

Start, Run, CMD, OK to open a command prompt:
(For Vista type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

Create a file in notepad named FIXANON.REG with the following contents:

You should have 3 boxes on the bottom in NOTEPAD.
1)Filename : FIXANON.REG
2)Save as type: all files
3)Encoding: ANSI
If you do not change it from txt type to All files type, then the file will actually be FIXANON.REG.txt, this won't accomplish the desired result.

------------------- Use text after this line -------------------
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
"restrictanonymous"=dword:00000000
------------------- Use text before this line -----------------

Double click on the file and say Yes to the merge into registry question.

Reboot the computer.

Yes it is XP HOME

The Node Type on my NEWVISTA machine is hybrid...

I hate messing with the registry, but I'll give JohnWill's solution a shot.

That is why you have the option to backup the registry first.

[hanick]

The registry solution did not work.

When I try to open the OLDXP share from NEWVISTA, I'm prompted for user name and password. When I enter the admin username and password it fails, and NEWVISTA\admin is greyed out in the username box. I tried using OLDXP\admin, but that doesn't work either.

Turn off any firewalls for debugging. If the firewall is the problem, you'll have to configure it to allow access to "trusted zone" addresses. Note that some firewalls must be completely uninstalled to stop them from affecting your networking.

Hold the Windows key and press R, then type CMD to open a command prompt.

In the command prompt window that opens, type type the following commands:

PING each remote computer by IP address, and if successful, PING by name. Open a command prompt as described above and type.

PING <ip address>
or
PING <computer name>

Where:
<ip address> - is the x.x.x.x IP address
<computer name> - is the computer name

A failure to PING is almost always a firewall configuration issue. Any failure to PING needs to be corrected before you go any farther.

Note: You can obtain the IP address and computer name of a computer by opening a command prompt (DOS window) and typing IPCONFIG /ALL. This should work for any Windows version. The IPCONFIG /ALL display will provide a wealth of useful information for debugging your network connection.

Check your Services are Started on all PCs:

• COM+ Event System (for WZC issues)
• Computer Browser
• DHCP Client
• DNS Client
• Network Connections
• Network Location Awareness
• Remote Procedure Call (RPC)
• Server
• TCP/IP Netbios helper
• Wireless Zero Configuration (XP wireless configurations)
• WLAN AutoConfig (Vista wireless configurations)
• Workstation

Note: You can check the services in Control Panel, Administrative Tools, Services.

All of these services should be started, and their startup type should be automatic.

If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running. Checking the event log is also a good idea here, there may be clues to what is failing.


All computers should be in the same workgroup for computer browsing to function properly. File & Print Sharing has to be enabled on any computer you wish to share files or printers from. You also need to actually share the resource in question from My Computer, right click on the drive/printer/folder, and select sharing.

If you encounter difficulties accessing computers that are visible in Network Places (Network and Sharing Center in Vista), make sure the computer being accessed has an account with the same name/password as the system connecting to it uses to login.

While the default NetBIOS setting is correct for normal network configurations, it's possible for it to be altered, and it costs nothing to make sure it's correct. NETBIOS over TCP/IP must be enabled for normal network browsing.

XP Home should never request a login/password. When it does, something is messed up. The only time I remember us finding a solution for such was with the registry fix to change RestrictAnonymous to 0.

There's probably some security suite (firewall) that asks for that information, but I have not heard of it. Other than that possibility I'm pretty sure your XP has registry corruption that we do not know how to find or fix.
