VPN not working after power failure

[Jason1975]

Hi All. We have a Windows 2008 R2 server acting as a VPN server. Everything has worked correctly for a few years until last week. (We had a power failure during the half term, but other than that no problems)The VPN connection is still working and seems to connect correctly, but after clients connect on they are not being assigned an IP address, so can't access the resources. The VPN connection being run on the client laptops is using the default VPN Windows 7 software.I can confirm that DHCP/DNS is working correctly internally with all machines getting a IP within our range.I am going to contact our ISP and see if they have changed anything without us knowing that may be stopping the traffic.Has anyone ever experienced this and if so any trouble shooting ideas please?Thank you in advance for any advice.Jason Edited November 1, 2017 by Jason1975
