intermittent reparsepoint attribute

We have a file server with a directory S:\ that is shared out as \\server\share. On the server we have the directories S:\rootDir1, S:\rootDir1\subDir, S:\rootDir2, and a junction S:\rootDir2\subDir => S:\rootDir1\subDir.

On an app server, I map M:\ => \\server\share, so the app server sees M:\rootDir1\subDir and M:\rootDir2\subDir

In powershell on the appserver, if I execute (Get-Item 'M:\rootDir2\subDir' ).Attributes, the results are very inconsistent. I can execute this command twice in a row, and the first time it returns Directory, and then immediately after it returns Directory, ReparsePoint. Does any one know how to get a consistent response of Directory, ReparsePoint ??
