# BitLocker Network Unlock FAQ
|
||
|
||
**Applies to**
|
||
- Windows 10
|
||
|
||
BitLocker Network Unlock enables easier management for BitLocker-enabled desktops and servers that use the TPM+PIN protection method in a domain environment. When a computer that is connected to a wired corporate network is rebooted, Network Unlock allows the PIN entry prompt to be bypassed. It automatically unlocks BitLocker-protected operating system volumes by using a trusted key that is provided by the Windows Deployment Services server as its secondary authentication method.
|
||
|
||
To use Network Unlock you must also have a PIN configured for your computer. When your computer is not connected to the network you will need to provide the PIN to unlock it.
|
||
|
||
BitLocker Network Unlock has software and hardware requirements for both client computers, Windows Deployment services, and domain controllers that must be met before you can use it.
|
||
|
||
Network Unlock uses two protectors, the TPM protector and the one provided by the network or by your PIN, whereas automatic unlock uses a single protector, the one stored in the TPM. If the computer is joined to a network without the key protector it will prompt you to enter your PIN. If the PIN is
|
||
not available you will need to use the recovery key to unlock the computer if it can ot be connected to the network.
