I have a gateway-to-gateway VPN between my datacenter (HQ) and a remote site. The VPN is between two Netgear UTM9S gateways. In HQ, I have a Windows Server 2003 DC as well as several Windows 7 Pro workstations. In the remote site I have two Windows 7 Pro workstations that used to live in HQ and connected just fine. Pings work fine back and forth between the sites
The root issue is I am unable to access password protected shares on the DC from the remote site. Further, I am unable to RDP from the remote site to any computer in HQ, where I can RDP from HQ to the remote site without issue.
I can browse shares on the DC (via its IP or FQDN), and can access the publically available ones like SYSVOL and NETLOGON. But anything that was password protected, or, that I created to help troubleshoot, ends with the message "...is not accessible. You might not have permissions to use this network resource... the specified network name is no longer available."
Below is an event log entry from the DC in HQ that I think is key to the issue, though I'm not sure what it may mean.
