There are a few options you can explore. I have a few questions to ask to help you form a strategy.
You said: "...no remote access is possible..."
Can you elaborate on this statement? Does that mean you cannot access these systems over your network at all, or do you do you mean you do not have a way to perform management tasks, like automated software installs over the network?
Are static IP addresses a requirement for you, or is DHCP an option?
Are you looking to just use basic (SMB) mode on these systems, or are you interested in standard or advanced security models?
Do you have any plans to adopt a management console, such as Altiris, SCCM, LANDesk, to take advantage of other AMT capabilities?
Offtopic: why does it say above the heading of this brandnew thread "1 right answer available and 2 helpful answers"?
So far, I am only talking to myself in this thread.
This gives you the ability to mark posts that you found helpful, and ultimately, answered your question. The idea is that if someone else has a similar problem and finds this discussion, they will be able to easily find the posts that solved your problem and save them some time.
> Are static IP addresses a requirement for you, or is DHCP an option?
No, static IP addresses are not a requirement. we just liked to idea of having a fixed mapping "pc_05_room_07_" has _always_ this adress 111.222._07_._05_, even the DHCP-Server is down.
> Are you looking to just use basic (SMB) mode on these systems ...
We found SMB-mode to be good, because it does not require a server or a certificate or sql-server. Budget restrictions...
> Do you have any plans to adopt a management console...
No, no time or money for that.
> "...no remote access is possible..."
There is no network connection between the main office and the remote site(s). At the remote sites there is known working gigabit-ethernet-connection using the onboard-networkcards included in the dc7800 and dc7900. The remote site are "isolated" and can not talk to our main office or the outside world. That cannot be changed at all.
There is a means of automated software installs at each site, but i can not go into details.
