I am running Samba 3.0.10 on a Sun 420R under Solaris 9.  To try to cut 
down the size of some user's roaming profiles I tried to re-direct the 
location Mozilla Mail uses to store *.msf files from the roaming profile 
to the user's UNIX home directory that we have mounted as h:\.  I was 
doing this in preparation to redirect more of the roaming profile files 
to the UNIX home directory - I was just starting small.

Anyhow, for the users that were changed I have see many "Windows Delayed 
  Write Failed" error messages.

I cannot provide any additional useful information right now - variants 
of SDBOT have been rampant on campus for weeks, and while the machines I 
administer have not been infected, attempts to infect them have kept us 
all busy  - and put the load average on my Samba PDC through the roof - 
here putting local firewall rules on the Windows 2000 machines (our 
networking group is unwilling to block the ports I want blocked between 
my networks and the rest of campus.)  Thus I've not had time to look for 
clues in the log files.  I had thought that it might be due to the 
unusually high load averages we have been running and once that was 
under control the problem would go away.
