Thanks to Drew Vonada-Smith the roaming profiles are working again. The
problem was that information stored in
HKLM\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Profilelist for the
user while trying logins while setting up the system got out of sync
with the actual server configuration. Deleting the entry for any
existing users let them login with a functioning roaming profile.
Unfortunately this did nothing about the fixed delays observed of 30s
and 15s. Here is part of the netlogon.log for the slow parts of a
domain user with a working (small = 2.5MB) profile. The 30s gap starts
at 10:05:53, and the 15s gap at 10:06:23.

I went through the event logs, and there was one interesting entry.
Also at 10:05:53 in the system log there was an event 7001 (1101),
"User Logon Notification for Customer Experience Improvement Program".
Have to run tcpdump on the server and see what happens at corresponding
times...

Nobody knows what causes these delays???
