Vista Cannot Connect to XP

[Iced Volvo]

Hi

We have a home network with several XP desktops which can all see a
workgroup shared directory on one XP machine we use for general storage.
Recently we got some new laptops with Vista on them.

When we try to connect to the XP based shared folders we can see them in the
explorer but when we try to explore or map a drive we are asked for
username/password. All the XP based computers can connect with no problem but
the Vista ones all fail even when correct username/passwords are entered.

And yes we have turned on discovery etc and yes we have tried disabling all
Virus and firewall sw!! This is such a basic thing to want to do you would
think that MS would have got it right with Vista!!

Any assistance with solving this problem would be appreciated.

Have a read of the above link re Vista File and Printer Sharing.

Permissions/Share info is there as well.

If using Norton, McAfee, Trend Micro I.S., make sure file and printer
sharing is enabled in THEIR firewall.

1st thing to do is make sure that the Workgroup Name of ALL the computers is
the SAME.

In Vista Network and Sharing:

Network Discovery: ON (So it can see the other computers)

Network set to Private (Public is for hotspots, airports, etc)

File Sharing: ON

Public Folder Sharing: ON (Vista’s Public Folder is the same as XP’s Shared
Docs)

Password Protected: OFF (unless you want to set up identical usernames and
passwords on ALL computers in your Network) If you have it ON, you will be
asked for a username and password when you try to access a Vista computer
from an XP computer.

Also, run the XP’s Home Network File and Printer Sharing Wizard to include
Vista in your “New†Network, even if you had an XP Network set up prior to
adding a Vista computer to it.

Hi Mick

Thanks for the suggestions, we had already done those. The problem is that
Vista cannot talk to XP, How is it possible for MS to produce an OS that
cannot talk to is most recent predecessor?

Solution is twofold dpending on which Vista you have:

METHOD 1: Through Local Security Policy:
NOTE: This feature is for Vista Business, Ultimate, and Enterprise versions
only. For Vista Home Basic and Home Premium see METHOD 2 below.

1. Open Administrative Tools.
NOTE: In Start Menu or Control Panel (Classic View).
2. Click Local Security Policy.
3. In the left pane, click the triangle next to Local Policy.
4. In the left pane, click Security Options.
5. In the right pane near the bottom, click Network security: LAN manager
authentication level.
6. Click the drop down box, and click Send LM & NTLM - use NTLMv2 session
security if negotiated.
7. Click OK.
8. Restart the computer.



METHOD 2: Hack the Registry:
NOTE: This is for Vista Home versions.

1. Open the Start Menu.
2. In the white line (Start Search) area, type regedit and press Enter.
3. Click Continue for UAC prompt.
4. In regedit, go to: -HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
5. In the right pane, right click LmCompatibilityLevel and click Modify.
NOTE: If it doesn't already exist, create a DWORD value named
LmCompatibilityLevel
6. Set the value to 1
7. Reboot

Voila now we can log into the XP shared dirs and printers from Vista. Why on
earth MS did not fix this one before releasing Vista or later patches for
either Vista and/or XP is gobsmacking!

Anyway problem solved

regards

jon

Strangely enough, I have no probs with the way I do it!
And I use it to set up other people's.
