[Samba] Home drives not being mounted. Samba 3.0.7 vs W2k TS

At a number of sites we are using Windows 2000 Server SP4 (APPSERVER) as a
Terminal Server and a PDC. All user areas are stored on a NetBSD 1.6.2
server with Samba 3.0.7 using security = domain and a named password
server. We've joined the domain from the Samba box (domain DOMAINNAME).

In general everything works fine, but when a number of clients log on at
around the same time (say 25 users at once), a fair proportion do not map
their home drive. Doing a "net use U: /home" at a later time
generally,
but not always, maps it.

It happens occasionally with 2.2.8, but we are getting feedback that 3.0.7
is much worse.

An extract of a log at the time of failure:
