Bypassing Smart Card Logon using Remote Registry

This VBscript prompts for a computer name or IP Address, connects to that system’s registry over the network and changes the scforceoption key to allow for immediate logon without a smart card. A PowerShell GUI version of this script can be found here, and there is also an updated version that works like a PowerShell cmdlet.

Many organizations now require CAC cards or another type of smart card to logon to workstations. A common way to enforce this is to use the Interactive logon: Require smart card group policy setting. When there is a problem with smart card authentication, this setting makes it difficult for troubleshooting.
