DB2 adminstration server was not started

I try to create a new database in DB2 instance, but I get:

DB2 adminstration server was not started. Run db2admin start ...



I run this command but I get the message that the server has been already started... :(

Let's re-create DAS:

DB2ADMIN stop
DB2ADMIN drop
DB2ADMIN create /user:your_user /password:your_password
DB2ADMIN start

And the issue solved.
