Any limitation of using Share folder in Streaming Server?

Hi,

Tested versions:

4.5.

Our problem is:

When we used Flash Media Developer Server 4.5 (Trial), we can use Share folder.

However, when we bought Streaming Server and deployed with same file structure, we can't use Share folder but Local folder only.

Is there any limitation of using Share folder in Streaming Server?

Configuration:

It's standard. we set fms.ini in Windows.

i.e.,  VOD_DIR = C:\Program Files\Adobe\Flash Media Server 4.5\applications\vod\media

Thanks.

Joseph
