Hi there,
Try removing the computer from the domain, re-join the domain, this will retain all custom configurations.
Additionally, try this too
Computer Configuration > Policies > Administrative Templates > System > Group Policy > "Configure Group Policy Caching" policy setting.
Enable this "Configure Group policy caching". This will allow your laptops to log in to your DC using a cached profile with the same DC credential, even your DC is not reachable.
Also, try,
Computer Configuration > Windows settings > Security settings > Local Policies > Security Options > Interactive Logon : Number of previous logons to cache ( in case domain controller is not available )
Enable Define this policy settings and set 10 logons cache count.
