Domain Server Trust

I have a Dell Server 2003 for small business server  32 Bit
I have another Dell Server 2008 R2 64 Bit
Both are on the same LAN with the same Gateway. (192.168.1.1)
Each is a Domain Controller.  Each has its own Domain.  THIS IS A NECESSITY dictated by the respective applications each one supports.  I CANNOT PUT THEM ON THE SAME DOMAIN.
I tried to set up "Trust" between the two domains, but failed with Error Message "Server 2003 for small business server cannot trust another domain".

I could upgrade the 32 Bit Server to Server Essentials 2012 R2.

MY QUESTIONS:

1 - Is Server Essentials 2012 R2 available in 32 Bit?
2 - Can I establish "Trust" between the Domains with Server Essentials 2012 R2?

Regards,

Biggles

What type of trust did you do?  Forest trust, or external trust?  Try an external trust if you didn't do it the first time.

External Trust

I have definitely set up a trust (external) between SBS (2003 and 2000 if you can believe that) and regular Windows 2008 R2 servers with mixed architectures (32 and 64 bit), so I know it can be done.  Did the error say anything more descriptive as to why it couldn't be setup?  Try initiating the trust from the 2008 side first.  If that doesn't work let me know.

I may have spoken to soon on this.  I thought I recalled creating a trust between SBS 2003 servers and 2008 R2 DCs, but this article from MS has proved me wrong.  I know I've setup 2003 to 2008 trusts though.

32Bit Operating systems for servers is going away like the DODO bird.  I've seen servers that won't even powerup with under 256GB memory.

Microsoft says SBS cannot do trusts.

You can't have trusts with SBS. Full Stop. Period. End. It is not possible.

Server essentials 2012 is 64bit ONLY, there is no 32bit version, however it can 'do trusts'.

I think this will put this question to rest:  I will have to buy a new Server.
One Final Question:
What is the most bare bones OS I can use?  I have no interest in setting up an Email Server.

Thanks for all your help.

The most barebones OS I'd recommend is Server 2012 R2 Standard.  64 bit of course.
