We have plan to evaluate Windows 7 Bitlocker on our domain PCs and laptops.  Some of the system models are old.  

Does a PC or laptop need to have a TPM chip in order for us to encrypt its C drive?  

Please advise.

No, you don't need TPM chip for bitlocker if you use USB stick to store its key.

no it must be a LOCAL drive i.e. USB KEY that is accessible on boot before the network is loaded.

What is the procedure if a user lost her USB key?  Assuming she has the recovery file being saved somewhere in our network drive.  

Please advise.

I should not need to do the above if I save the recovery key to a file and copy it into a save location on the network, right?

From what I have learned so far, a Bitlocker encrypted laptop will require the USB for start up.  If this USB drive is lost, can the user still access her data in the encrypted C drive with only the recovery key from the file I saved in the encryption process?  This is what I am trying to ask.  

Please advise again.  Thanks.
