MSDTC and Win2K3: clear

I'm trying to clear some data from a SQL DB table, but i'm getting this
error:
I'm just running a Delete Query using Date Diff function. I read in some
web site that this maybe a problem with SQL Server Management Tools. I
appreciate any help to get around this and any suggestions would be great.
Msg 9002, Level 17, State 4, Line 2
The transaction log for database 'EventSentry' is full. To find out why
space in the log cannot be reused, see the log_reuse_wait_desc column in
sys.databases
Thanks for answering.Fialoa,
Your delete transaction is writting too many log records and filling it up.
If you want to be able to recover then you need to make the log bigger or
make your delete statement work on a smaller subset.

SQL Server has to log every data modification operation, every insert,
update and delete. If the log is full, nothing can be written to it and no
data modifications can be done. This has nothing to do with the tool you are
using.
Just do what the messages says. Look at the sys.databases view and tell us
what the log_reuse_wait_desc says. Also look at the recovery model
SELECT log_reuse_wait_desc, recovery_model_desc
FROM sys.databases
WHERE name = 'EventSentry'

Log_Reuse_Wait_Desc = NOTHING
Recovery_Model_Desc = SIMPLE

doing.
How big is your log file, and is it set to autogrow?
You can get the information in the sys.files view in the database that is
having the problems.

Almost every client I have been at still has the defaults for data/log size
and growths (2MB and 1MB growth for data and 1MB and 10% growth for tlog,
IIRC). Makes me look good when I have them defrag the hard drive and pick
up a big perf gain. :-)

We also try and size our data and log files with limited growth. I have seen
problems with an unlimited log and percent full log alerts.
How much improvement would a disk defrag give you on todays raided disks?

We do that as best we can. We have alerts fired if the data file expands and
then we would look at the log size too. We also would get messages if the
log does get full.
My question is to see how much improvement we might get by defragging.
