XP SP3 have acessd denied to shared folders of Vista SP2

[kremlincrackers]

Hi.

I have 2 PC's. One with XP SP3 and other with Vista SP2. On vista SP2 have 4 discs shared like i have before on Vista SP1...

On vista Sp1 the share works wonderful... when i updated to SP2 the share don't work anymore.

The XP give me the message "Access Denied". The configuration is the same like before...

Both windows are up to date.

Anyone have a solution for this?

Thanks
