Its throwing the same error,

TABLES cannot be dropped

Msg 3609, Level 16, State 2, Procedure sp_MSdrop_pub_tables, Line 17

The transaction ended in the trigger. The batch has been aborted.

The only configuration change that I made apart from what mentioned in my study guide was that the SQL Server agent service was not running and I started it from service console. I tried stopping it and then disabling the publilsh but to no use.

Thanks,

Prakash.
