Server har skiftet "Network Location" til "Private"

 Powershell:

Get-NetConnectionProfile

Genstart NLA så skifter den selv til "Domainauthenticated" hvis DC er oppe

NTP time service i Active Directory

F.eks. (på DC):
w32tm /config /update /manualpeerlist:"0.pool.ntp.org,0x8 1.pool.ntp.org,0x8 2.pool.ntp.org,0x8 3.pool.ntp.org,0x8" /syncfromflags:MANUAL
net stop w32time
net start w32time
w32tm /resync

Check NTP servers connection : w32tm /query /peers

Laptop som ikke er på AD så tit :
w32tm /config /update /manualpeerlist:"pool.ntp.org,0x8" /syncfromflags:MANUAL,DOMHIER

Check time sync: w32tm /stripchart /computer:192.168.0.10 (servers IP)

PS!
Time synchronization may not succeed when you try to synchronize with a non-Wind...
