You are a network administrator for TestKing. The network contains two Windows Server 2003 computers named TestKingA and TestKingB. These servers host an intranet application. Currently, 40 users connect to TestKingA and 44 users connect to TestKingB. The company is adding 35 employees who will need access to the intranet application. Testing shows that each server is capable of supporting approximately 50 users without adversely affecting the performance of the application. You need to provide a solution for supporting the additional 35 employees. The solution must include providing server fault tolerance. You need to minimize the costs and administrative effort required by your solution. You add a new server named TestKingC to the network and install the intranet application on TestKingC. What else should you do?
