Problem viewing/accessing files on server

[derakicksyou]

I just updated my work computer to Snow Leopard (from 10.4.whatever).
Before, I'd connect to my works server (which is PC based), and access all my files from there.
I still do that, but for some reason, some folders are showing up empty.
When I jump onto a different computer, all the content of those folders are still there.
Not sure what I should do - one folder in specific is full of content that I need to access daily.
Any ideas?

Sounds permissions based. 10.4 did not recognize ACL permission but 10.6. Perhaps the system admin could assist you with the request.

In the terminal us the ls -la command to determine the current permissions including ACL permissions on the windows share.
