EXEC RemoteServer.Database.dbo.StoredProcedure @Parameter1, @parameter2

Can u explain in detail..?
Concept:
---------------
Have to connect to more than 1000 servers....
Using test server we have to execute in remote ( remote tables are not available in this server)
First have to connect to the remote, select the right database after that execute the queries.
To do this we have to maintain 2 or 3 loops right?
Thanks,

Why?
One table with list of servers, databases, SP names and probably list of parameters will do it all.
Cursor through this table, build the query from names stored there and EXEC sp_executesql @Query
