The Guide is good--but essentially incomplete in a few VERY important aspects.
0. CTRL-ALT-DEL will bring up the task manager. New tasks can then be started. 'Control' will start the control panel. 'cmd' and 'explorer' are also handy. Any executable you can get to with explorer can also be attempted to run. Internet Explorer can be run in this fashion--as can a number of driver install programs. SBSsetup log and also be viewed. This is invaluable to know.
1. DCOM must be properly configured on the source server, as per
http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/SBS_Small_Business_Server/Q_25087329.htmlOn the source server, Click Start / Run and type DCOMCNFG.EXE and hit ENTER.
In the right-hand pane, double-click Component Services, then Computers.
In the right-hand pane, right click on My Computer and select Properties
Click the Default Properties tab
Click to check the box: "Enable distributed COM on this computer".
Click OK.
Reboot the source server.
If it is not, the destination server will whine that the Migration Wizard has not been run--and you may do a bunch of fruitless Wizard/Reboot iterations till you discover that
2. The changes requested to the network configuration pre-migration are EVIL and need to be dealt with in much greater detail.
My SBS setup is multi-site. Disabling RRAS will trash any static routes--these need to be documented and re-created manually. Forewarned is forearmed.
Multi-site also means multi-homed--and possibly the source server may have more than one DNS entry.
THE FQDN OF THE SOURCE SERVER
MUST RESOLVE TO ONLY ONE AND ONLY ONE ADDRESS, ON A CLASS 'C' SUBNET SHARED BY THE SOURCE AND DESTINATION SERVERS.
If it does not, DCPROMO will fail--and you will be required to reformat the destination server. Which can be very time consuming. You may also be required to restore the system state of the source server (fortunately I did not) which may introduce other possible problems that may need registry hacks.
3. Multi-site AD replication MUST be tested BEFORE migrating and AFTER reconfiguring the source server's network. The migration process will attempt to replicate the AD--failure results in VERY long delays and eventually a message asking whether or not to ignore the failure. CTRL-ALT-DEL | task manager | new task| control | administrative tools | AD Sites and Services can be accessed to determine if replication can be forced on the destination server. Replication can be tested on the source server during the migration. Issues can be sorted out and allow the migration to continue.
Given that multi-homed SBS boxes were the desired configuration, why does the migration REQUIRE trashing the existing routing setup, instead of migrating it?
