We have deleted distribution (system database) data files manually.
Now I'm unable to do below process(How can I delete logical instance of distribution).
Disable publishing and distribution wizard
An Exception occurred while executing a transact-SQL
Database 'distribution' does not exist. Make sure that the name is entered correctly.
Changed database context to 'master'.
I have tried with below procedures but the problem was not rectified
EXEC sp_removedbreplication @publicationDB
EXEC sp_dropdistpublisher @publisher
EXEC sp_dropdistributiondb @distributionDB
EXEC sp_dropdistributor
Looking forward to receive suggestions.
