Dear All,
i'm planning to drop all the non clustered indexes (as they are not congigured well) on production database, and run the latest script to create fresh non clustered indexes on specific columns.

now my doubts are
1)will the replication affect with dropping and recreating of indexes?
2)query to drop all the non clustered indexes on that database....
can i use the query delete from sysindexes where indid>1
will the query works for me to drop all the non clustered indexes?
3)is it necessary to generate a snapshot again after creating the new indexes? or can i drop and run at subscriber also?

please guide me in this regard

Not unless you want an inconsistent database with severe integrity issues and potential corruption poblems.

Drop indexes using the DROP INDEX command. Never, never, never directly modify the system tables.

Well, If replication is running and you drop/create non-clustered indexes. You might face performance problems as it also has to replicate to Subscriber increasing your log space.
