I've three server
1. Server-1
2. Server-2
3. Server-3

All three server have sql server 2005 developer Edition (SP4) installed.

Now the senario is :
Sever-1(Principal Server) database is mirrored in Server-2(Mirrored Server).I've set a replication in server-1 to server-3. Now if Server-1(pricipal server) goes down then Server-2 will be up.but what will be my replication set in server-1? would I have to create it again in server-2 to server-3 or there is any other way? please suggest.

I expect someone like Perry Whittle will answer this in more detail, but when Server-1 goes down, your Subscriber databases(s) on Server-3 will no longer receive transactions (or snapshots - you didn't state what type of replication you are using).
You then have a choice of either bringing the failed Server-1 back up (once you've fixed whatever problem caused it to go down) and replication should continue from where it left off, provided that your Subscription expiry period has not been breached (in which case you'll need to Reinitialise the Subscription)...or...you can set up Replication afresh on Server-2.
Bear in mind that if you choose the second option and you want to create the Subscriptions on Server-3 with exactly the same names as before, you'll need to drop the original subscriptions first.

Thanks Lempster for your kind reply.

I'm using Transactional Replication.

Now please let me know, is there any option to create failover replication? if yes, how to do that?

Failover Replication?
Do you mean Replication when the databases participating in the replication topology are on clustered instances? If so, replication should continue when a failover occurs with a small delay during the actual failover.There are no additional steps involved in setting up replication on a FCI (Failover Clustered Instance) as far as I know.
