reducing size of log file

Hi,
I have SQL 2000 running on W2000.
Some of my data has huge log files - eg 5Gb log for a DB of 50Mb.
Under properties, it reports that it is 95% space.
How can I reduce the size of these?
I have tried the shrink option bu it doesn't help.
Many thanks
NEILYou need to backup log before shrinking it
BACKUP LOG database_name WITH TRUNCATE_ONLY

I have bvacked up log - using EM Backup Database... and this has reduced the
actual used size even miore, however it still occupies 5Gb of disk space.
I can't seem to use the DBCC commands described in the article supplied, can
you tell me how to do this? If I type DBCC followed by anything, I get dbcc
is not recognised ...
cheers,
NEIL|||Hello,
Backup Log will clear up all the inactive postion of the log but will not
reduce the physical file. To reduce the physical
file you may need to SHRINK the LDF file using DBCC SHRINKFILE command. Take
a look into books online about
DBCC SHRINKFILE.
One more thing is schedule a frequent transaction log backup. This will
ensure that your LDF is not growing heavily as well as
make sure you have backup files to recover the database when required.
Thanks
Hari

What application are you using to execute the DBCC command?

I used a CMD screen to do this - I presumed it was a DOS type command.
