We have a domain controller in 1 location and a member server in an other location. They are both server 2012 R2. The 2 are connected through an ipsec vpn tunnel. On the domain controller we have set that the policy "Interactive logon: Number of previous logons to cache (in case domain controller is not available)" to 50 logons.
Here's the problem:
We logon to the memberserver through rdp. When the vpn tunnel is down, we cant login because the server says there's no domaincontroller available. We have checked that the gpo is applied bij going to the registry key that controls the number of cached logons. It says 50, so the gpo is applied.
Any suggestions on how to resolve this are very welcome.
