Hello I installed INS1 on Node A and INS2 on Node B. But the management studio is not installed on Node B. Iam trying to install client tools on node B (I have servers n Tools folders) it is giving me the following message Name: Microsoft SQL Server 2005 Tools (64-bit) Allowed Action: Maintain(Action is only available from Add or Remove programs) Reason: cannot maintain product, to maintain the product go to Add or Remove programs. After this message if i click next Iam getting below error: TITLE: Microsoft SQL Server Setup ------------------------------ None of the selected features can be installed or upgraded. Setup cannot proceed since no effective change is being made to the machine. To continue, click Back and then select features to install. To exit SQL Server Setup, click Cancel. So tried through add or Remove programs.
