Network requests user’s password each time.

Hi,

Recently one user has been getting the same issue. She can log into the network fine on her, however when she attempts to access a network drive/folders. It begins to request the same username and password for the network. This also happens for her Outlook as well, it requests the username and password.

Also due to this issue, she cannot print. I have to keep adding the printers to her machine each time this issue happens. Again its a access denied.

Any thoughts and advice on this strange issue? Is it possible the SID on this user has corrupted somehow?

Forgot to add this is for XP and server 2003
