samba - Aug 2005 - Errors... unknown problem?

My network currently uses samba version 3.0.14 and doesn't seem to have any 
problems but alot of my logs repeat the following error message:

[2005/08/09 09:29:42, 0] 
rpc_client/cli_trust.c:change_trust_account_password(248)
2005/08/09 09:29:42 : change_trust_account_password: Failed to change 
password for domain SPICE.

There shouldn't be any passwords changing.
What causes this and how might I verify that there is or isn't a problem?

I found several others who have asked the same question of this same error 
but have not been able to find an answer or a solution.
Cheers,

Hi,

I am experiencing very slow writes over samba.  We have a modest linux 
network (about 6 servers) and a medium sized office (20-30 windows 
boxes).  We have had a single linux file server that has done us yeoman 
service for several years.  It is running RH 7.3.  I am trying to set up 
the next generation file server with a huge (to me anyway) 2TB Promise 
VTrak 12110 RAID disk.  I've installed Fedora Core 3 and got the file 
server up and running and it works fine... except it seemed slower than 
the older system.

So, I downloaded "Performance Test" from www.passmark.com that tests 
things like hard drive speeds under Windows.  What the test told me was:

OLD SERVER
sequential read:   6.2 MB/s
sequential write: 6.4 MB/s
random seek + RW: 2 MB/s

NEW SERVER
sequential read:   8.9 MB/s
sequential write: 0.38 MB/s           <=====   *OUCH!!!*
random seek + RW: 15.9 MB/s

So, the read time is good, its just the sequential write time that 
really sucks.  What I observed while running this test was the CPU went 
up to 99% using "top" during the write time.

The new server is a Dell rack-mount server with a Xeon 2.8GHz CPU with 
2G of RAM.  My smb.conf is below.

I don't really know what I'm doing in debugging Samba... its always 
worked fine for me in the past and I've never experienced this kind of 
problem so I'm not sure where to start.

Any advice would be appreciated!!

Don
