When you run a DBCC SHRINKFILE command in SQL Query Analyzer to shrink the specified transaction log file of a database, the transaction log file does not shrink, and you may receive the following error message:
Cannot shrink log file <transaction log file ID> (<transaction log file name>) because total number of virtual log files cannot be fewer than 2.
When a transaction log file has two virtual log files, you cannot shrink the transaction log file by using the DBCC SHRINKFILE command.
