WebDAV folder not working for shared review

I want to create a shared review using my G5 Acrobat 8.1.2 Leopard 10.5 My IT department is using SMB network protocol. When trying to configure location path, I select the browse and find the path but will not create the path. I type in the location path and it still says it cannot be verified. My IT person has successful done it from his Intel computer but not on G5. He also has admin rights. Is there anyone out there have any documentation about any bugs or know what we are doing wrong or if there are permission problems with our set up? Out IT has pretty much blocked us out of saving anything to our harddrives. Could this be the problem?
