don't understand driver validation results

I am new to Norton Ghost, ver. 14. After running the driver validation test, I received the following results, which I do not understand.

 

The following devices do not have drivers in the Symantec Recovery Disk.

 

Packet Scheduler Miniport

Symantec Network Security Miniport

 

A detailed information about these devices is given below

 

Description : Packet Scheduler Miniport

Class : Net

Class Guid : {4D36E972-E325-11CE-BFC1-08002BE10318}

Hardware Id : ms_pschedmp

Hardware Id : ms_pschedmp

Description : Symantec Network Security Miniport

Class : Net

Class Guid : {4D36E972-E325-11CE-BFC1-08002BE10318}

Hardware Id : symc_SymIMmp

Hardware Id : symc_SymIMmp

If these drivers were relative to some hardware, I could probably figure it out, but these results have me totally confused. Can anyone help me understand this?

 

Thank you!!!
