Situation: Migration of an NT4 domain to Windows Server 2003 AD consisting of 1 PDC/fileserver, 1 BDC, 3 network printers, 20 computers (mostly WinXP, some Win2K), 8 employees, no roaming profiles. There is no full-time administrator and the person administering the domain is doing at most account management and patching.

I've been asked to perform the migration. Additionally, they will introduce a new server into the network. I have three options:
1) Start a new AD domain from scratch and do not migrate any users
2) Start a new AD domain on the new server and use ADMT to migrate users/computers/printers
3) In-place upgrade of the NT4 PDC to Windows Server 2003 and use new server as second DC, however then the GC will be on the older former NT4 PDC.

I'm also planning to install SUS for patch management.

Anybody got any recommendations regarding this? Would be my first AD migration.
