Sorry not to be able to answer your question directly, but your question doesn’t contain enough information, and would leave me making assumptions – so instead, here are some specific questions to clarify the situation, and perhaps shed some light on it.
1) “During a Remote Desktop session, the Pavilion…” Can I assume that the Pavilion has connected to TermSvr on the VAIO? What user name is being used, and what are its privileges?
2) “the Pavilion does not recognize VAIO directories/drives” Do you mean that they are not visible? Or do you mean that you see them, but cannot open them?
3)Are you in a Domain with Group Policies set? As with question 1, are there different user rights?
4) Have you looked at any of the logs?
Write back and let us know.
