I have just upgraded our server from SBS2003 to SBS2008. I had several workstations accessible with RDP from home computers. Everything worked fine before the upgrade.
Now, I can access the server with RDP but not the individual workstations.
Workstations have a DHCP reservation.
Router uses port translation to connect to individual workstation ie. Port XXX1 -> 3389 _> workstation IP
I have given the users permission via the server user accounts to use RDP to access their workstations.
I have double checked all settings. RDP access on workstations is greyed out BUT checked and add users show that domain name/user has access.
I can access the workstations using RDP from any other computer on the network (internal) using the internal ip and loggin in as the ws user.
I'm sure this must be a firewall issue or group policy issue. Everything is standard install.
