PCs without CD-ROMs - ManagementException: Provider failure

[joegasper]

I've got a bit of a pattern on my systems that don't have optical media drives. Most of them (not all) and across several models (Dell), produce the following error in the service errorlog.txt and display an error for the CD on the individual system webpage.

System.Management.ManagementException: Provider failure
at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext()
at Lansweeper30.sweeperthread.GetWMI(String Querystr, String Table, clsComputer mycomputer, String section, clsThreadinfo Threadinfo, SqlConnection& sqlcon)

Everything keeps working, the service doesn't crash, and the rest of the scan information is complete.

The provider failure can happen for 2 reasons:

- You don't have any cdrom's, so the wmi class isn't implemented on this computer
- You have a cdrom but the wmi class for scanning the cdrom is corrupt, or there is another wmi error that can be solved

So I don't have any correct answer for leaving the error in or out of the errorlog file.
