Hi there, I just set up a new workstation at a remote location that is a member of our office domain and is connected through a site-to-site IPSEC VPN (Microtik in our office, Cisco firewall on the remote site). The VPN connection seems to be working well, with most communication having no issue, but we have a piece of software that relies on DCOM that just will not work. Additionally, Group Policy fails to update on this workstation. For both issues,"The RPC Server is Unavailable" is the stated problem.
Firewalls on both sides have been set to allow all IP traffic through unrestricted over the VPN link, and no other software firewalls are in place. Still, taking that workstation to our office and connecting it to our LAN does work, making me think there is something else with the Microtik setup that could be interfering.
Does anybody have any experience with this problem or know what might be the issue? Your help would be greatly appreciated!
