How do I reproduce the data in Computer Management/Shared Folders/Sessions?

C#

VB

I have a requirement to scan 750 (windows 2003) file and print servers for details of the connected sessions. I thought I'd cracked this using the Win32_ServerSession Class until I discovered that a session with an ActiveTime of around 15 hours (from the Win32_ServerSession Class) was showing with a Connected Time of around 62 days in the Computer Management/Shared Folders/Sessions GUI!

I can get from the LogonID of Win32_Session via the Name in Win32_LoggedOnUser and thence to the Win32_ServerSession Class but that's one remote WMI call to get a list of sessions and then two further remote WMI calls per session. That could easily take 15 minutes per server!

So, does anyone know how to get the data shown in the Computer Management/Shared Folders/Sessions GUI programmatically (preferably in VB.Net but C# would do).

Thanks
