I'm required to add a new application server on an existing production farm where there are hunderds of active users accessing the portal sites currently.
My farm toplogy is like this :-
2 WFE
1 SEARCH & INDEXING
1 DB Cluster
I want to know what should be the recommended way (like sequence of shutdown of iis, etc) of adding a new application server to the existing farm and how much downtime should be required.
