VPN works the best. You need to set up the trust between the two companies, a very good Internet connection and lots of calls. The other way is to create or use a cloud system. Ricardo A. Maturana Twitter: @rmaturana
How can I grant read/write privleges to the Revit Server to everyone? The other office does not have a domain controller. How can I set up a trust relationship between the remote workstations and the Revit server? Thanks.
