nsure that there is enough disk space available, and that the account under which the Snapshot Agent runs has permissions to write to the snapshot folder and its subdirectories.

Getting the following error when i execute the script :

IF ( SELECT OBJECT_ID('tableABC') ) IS NOT NULL
BEGIN
      ALTER TABLE tableABC
      ADD flag_column nchar NOT NULL DEFAULT 'n'
END


Its giving Msg 21331, Level 16, State 1, Procedure sp_MSreplcopyscriptfile, Line 49
Cannot copy user script file to the snapshot folder at the Distributor (copy "IF ( SELECT OBJECT_ID('tableABC') ) IS NOT NULL
