Domain Trust Between 2 Domains on different network via VPN

SBS does not do trusts. It is one of the restrictions enforced on SBS to get the price break compared to the standalone components. You mist either join the other machine to the SBS domain or you must upgrade from SBS to full products.

Cliff, I did here something about that.  I will join the windows 2003 server r2 to the SBS domain.  Thanks

are you able to ping server to server?
have you tried to create explicit trust relationship?

I can ping back and forth with no problem....i also created trust between the 2 and still nothing.

Taken from the SBS FAQ:


Are there any design constraints in Windows SBS 2008?
The design constraints are similar to previous versions of Windows SBS. They are:

No more than 75 users or devices.
The Standard server must be the root domain controller of the forest.
The Standard server must hold the flexible single master operations (FSMO) roles.
The Standard server must be a global catalog.
There can be no inter-forest trusts or child domains.
Terminal Services Application Mode is disabled on the Standard server.
The Premium server must be a member server or additional domain controller of a Windows SBS 2008 network.


Here is the URL, question #3: http://technet.microsoft.com/en-us/sbs/cc817589.aspx

This is a SBS 2003 server.  Is it true that the SBS 2003 cannot do a trust because its not the full verison.
?

I pulled that straight from the SBS FAQ. note the "there can be no inter-forest trusts or child domains."

I posted that as an answer. I've then posted MS documentation backing up my answer. So, third time's a charm: NO TRUSTS CAN BE MADE WITH SBS!!!

Since no trust can be made with sbs, can I add the other windows 2003 r2 server as a secondary domain or memeber?

Straight and to the point....thanks
