-Problem-

Windows Vista can’t connect to a Windows XP computer file share. You keep getting a logon unsuccessful error message even though you are using a correct username/password.

-Solution-

Method 1:

NOTE: This method is for Vista Business, Ultimate, and Enterprise versions only. For Vista Home versions see the second method.

1. Open Administrative Tools. (In Control Panel after clicking on “Classic View” on the left side bar)
2. Click Local Security Policy. (click continue on security dialog)
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 about 3/4 the way down, double 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: (required for home editions of Vista, not recommended for novice users)

1. Open the Start Menu.
2. In the white line (Start Search) area, type regedit and press Enter.
3. Click Continue on the security dialog.
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
