I'd like to be able to see Win32_PhysicalMedia information when logged in as a Limited User in XP (not admin rights). It works ok when logged in as Admin, WMIDiag has just given a clean bill of health, and Win32_DiskDrive class produces information correctly, but Win32_PhysicalMedia produces a count of 0 for this code set WMI = GetObject("WinMgtmts:/root/cimv2") set objs = WMI.InstancesOf("Win32_PhysicalMedia") wscript.echo objs.count Alternatively, if the hard disk serial number as found on the SerialNumber property of the physical drives is available in another class which I can read as a limited user please let me know. I am not attempting to write to any property with WMI, but I can't read this when running as a Limited User. Interestingly, DiskDrive misses out Signature property, which would do for my application when run as a Limited User but is present when run from an Admin account.
