Solved: Xp accesses Vista but Vita can't access XP

SOLVED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I GOT IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I had to go into:

Administrative tools> Security Settings>Local Policies>Security Options. on
right and window select "Network Access:Sharing and security model for local
accounts" and select "Classic - local users authenticate as themselves."

Next was because my Windows XP logons automatically without a password,
which also affects remote desktop.

To correct this I did the following:

You can disable blank password restrictions by using a policy. To locate and
change this policy:
1. Click Start, point to Run, type gpedit.msc, and then click OK to start
the Group Policy Editor.
2. Open Computer Configuration\Windows Settings\Security Settings\Local
Policies\Security Options\Accounts: Limit local account use of blank
passwords to console logon only.
3. Double-click Limit local account use of blank passwords to consol logon
only.
4. Click Disabled, and then click OK.
5. Quit Group Policy Editor.

I'm happy
