Can't transfer master roles from 2003 to SBS 2003 - RPC server unavailable

I thought I was on the home stretch bringing my 2003 SBS server back into my existing domain but after transferring the master roles FSMO to the SBS 2003 server, the Continue Installation process claims that it does not have all the master roles.  I don't want to seize the role because I need the other server to stay in production.  Netdom query fsmo on the SBS server gives RPC server is unavailable.  Netdom from the 2003 give incorrect parameter.. :|  When I try to connect with NTDSUTIL to the SBS server from the 2003 Enterprise server, it errors out with an RPC error: DsBindW error 0x6ba(The RPC server is unavailable.)  I've started the RPC services but that didn't help.  DNS is installed on both servers and both servers are currently pointing to the SBS server.  Any ideas?

You have some issues with either DNS or ports
To check DNS, make sure you have secondary zones on both sides for each other
Also, make sure ports required for AD are open
Following ports should be open
DNS 53 tcp udp
WINS 42
LDAP 389
GC 3268 3269
RPC 135
Download the port query (portqryui) from Microsoft website to check if required ports are open or not
In portqry, you have to enter IP/name of target DC and check the ports, If any of these ports are not listening or filetered, you have the number
Make sure these ports are open on router/firewall

Thanks

Thank you very much.  It looks like Windows Firewall was on and was blocking RPC.  I just turned it off for now and am able to connect from the 2003 Ent to the SBS with ntdsutil !!! :)  However, events now show a schema mismatch.  I'm planning to tranfer all roles back to the 2003 server, may even remove AD for the SBS, then bring it back in again...

Actually, the swing migration told me to transfer the roles and then reboot - which I did.  What I did not do was to wait until the roles had syncronized before rebooting.  I ended going back and rebuilding the new server and this time when I transfered the roles, they came across just fine - then I rebooted and the rest went OK.  Thanks.
