My database is SQL server 2000. My database size is 27GB. My tempdb size is 100MB including tempdb.mdf=98MB and tempdb.ldf=3MB). Both tempdb.mdf and tempdb.ldf files are auto grow by 10% with unrestricted size. The free hard disk is 12GB. Users can not query. Please give me your advice.
Watch Question

When you can get all users out, run the following commands -

USE tempdb
DBCC SHRINKFILE(1, 10240)  -- reduces tempdb.mdf to 10GB

It would be advisable to run these statements in a scheduled SQL job every weekend to keep the tempdb size down on an ongoing basis..

tempdb is simple recovery mode, you cannot do BACKUP TRANSACTION on tempdb ...
also, doing a shrinkfile on tempdb is not really good action for regular basis... as it will need to grow again.

you will need to identify the reason of why the tempdb needs so much space that it runs out of space.
note: if you get that message, it actually means that you are requiring tempdb space faster than sql server can allocate it (by growing the files of tempdb)

so, instead of trying to cure the symptoms, solve the underlying problems, which are:
* non-indexed queries with group by and order by
* unnecessary temp tables
* long lasting cursor queries
* etc ...
