J'ai seen various différent questions for this problem floating around mais soit le circumstances arent le même ou le solution doesnt work so thought i would post it to see si anybody has tout suggestions.
Various domain PCs et laptops appear to randomly give le connection name of "lewis.local 2(Unauthenticated)" - lewis.local being our domain - et provides an exclamation mark où le network type logo is normally shown.
This aussi appears to happen chaque time connecting via vpn.
Our setup is:
- 2 servers les deux running windows server 2003 R2 (x32)
- main server has AD, DNS et DHCP installed
- IPv4 on approx 30 client machines (some wired, certains wireless)
If anybody has tout thoughts on solutions i would appreciate it. J'ai tried removing tous mais AD server roles, resetting tous of le systems et nothing.
It doesnt prevent anything depuis working juste like a domain connection le plus of le time however it is getting fustrating!
Also dont know si it could have anything to do avec it mais le DHCP server seems to have assez a long lead time on issuing le IP address to le client.
La connexion au domaine s'affiche comme « non authentifiée »
Re: La connexion au domaine s'affiche comme « non authentifiée »
One possible reason for this issue is quand le machine account password gets out of sync avec le domain controller.
Cela peut happen, par exemple, si le computer account in Active Directory is manually removed et re-added, ou si le client machine has been restored to an earlier point in time (machine account passwords are automatically changed chaque 30 days).
What worked for me was to redéfinissez le machine account password manually by executing [P1](https://technet.microsoft.com/en-us/library/hh849751.aspx) in an elevated(!) PowerShell:
```
PS> Reset-ComputerMachinePassword -Credential MYDOMAIN\SomeDomainAdminAccount
```
After rebooting (or disabling et re-enabling le network card, si you ne want to reboot), le *(unauthenticated)* note should be gone.
