CodeB Credential Provider V2 can show the computer name (and domain) on its logon tile, plus a “System information” link with date and time, IP addresses, gateway, DNS servers, DHCP/static and MAC address per network adapter. Optional “Release IP address” / “Renew IP address” links can be added. Both are off by default and switched on with LogonScreenInfo and LogonScreenIpControl.
What does the CodeB tile show at the logon screen?
With the feature switched on, the CodeB logon tile shows the computer name and domain — the Windows “.\” trick is not available on the CodeB tile, so this is how a user or helpdesk sees which PC they are at. The System information link opens:
| Item | Shown |
|---|---|
| Computer | Computer name and domain. |
| Date and time | Local time, time zone and UTC. |
| Per active network adapter | IP addresses, gateway, DNS servers, DHCP or static, MAC address. |
It is shown at logon and unlock only.
How do you show the computer name on the Windows logon screen?
- Set
HKLM\SOFTWARE\WOW6432Node\CodeB\Config\LogonScreenInfo=1(REG_SZ), or tick the option in the CodeB Admin Console, tab Logo & settings, and press Save settings. - For many PCs, use a Group Policy registry preference.
- Lock the PC or sign out: the CodeB tile now shows the computer name and the System information link.
Can users release and renew the IP address at the logon screen?
Only if you allow it. Set HKLM\SOFTWARE\WOW6432Node\CodeB\Config\LogonScreenIpControl = 1 to add Release IP address and Renew IP address links. They appear only while LogonScreenInfo is on. They are off by default because anybody at the logon screen could take the PC off the network.
Is it safe to show network details at the logon screen?
That is your decision, which is why both switches are off by default: some environments, for example CMMC customers, must not show network details before logon. Nothing else can be started from the logon screen — no window, no command prompt — only the information view and, if allowed, the two IP links.
| Value (REG_SZ) | Default | Effect |
|---|---|---|
Config\LogonScreenInfo | off | 1 = computer name and System information link on the CodeB tile. |
Config\LogonScreenIpControl | off | 1 = Release / Renew IP address links (needs LogonScreenInfo). |
Frequently asked questions
How do I show the computer name on the Windows logon screen?
Set HKLM\SOFTWARE\WOW6432Node\CodeB\Config\LogonScreenInfo to 1, or tick it in the CodeB Admin Console under Logo & settings. The CodeB tile then shows the computer name and a System information link.
Can I check the IP address at the Windows logon screen?
Yes, with LogonScreenInfo on. The System information link shows IP addresses, gateway, DNS servers, DHCP or static and MAC address for each active adapter.
Can users release or renew the IP address before logging on?
Only if you set LogonScreenIpControl to 1. The links are off by default because anybody at the logon screen could take the PC off the network.
