We had a bunch of NTFS LUN's on a server that crashed (2003x64/Snapdrive 4.2.1).  We are trying to move the LUNS to another server(Snapdrive 6/Win2k3x64).  To do this we did the following:

1) Unmap old initiator from lun

2) Zone new server to the Netapp filer.

3) Try to use connect disk from new server to the lun

4) This gives a error saying drive notification timeout

To debug this more, I  opened Disk Management.  The disks do not show up there either.  But they show up as LUNs under Device manager.  Why do the LUN's show up in Device Manager/Disk drives but not in Disk management?     

Thanks
