SUMMARY
If you follow the default Microsoft Cluster Server (MSCS) installation settings, you will get a 32-second delay the first time you try to access the COM+/MTS object.
MORE INFORMATION
The nature of this problem is described in the following Microsoft Knowledge Base article:
288886 PRB: Delayed DCOM Activation on Multihomed Computers
However, the solution that is provided in Q288886 does not apply to MSCS and may cause Microsoft Distributed Transaction Coordinator (MS DTC) access violations.
Two possible solutions are available (note that changes should be made on both nodes).
Method 1: Disable WINS on the Private Network Interface
Disable the Microsoft Windows Internet Naming Service (WINS) for the private network interface cards (NICs) for node communication. This will prevent private NICs' IP addresses from being broadcast over network. Hence, the client can only access the client NIC's IP. For additional information on WINS configuration, click the article number below to view the article in the Microsoft Knowledge Base:

Method 2: Change the Binding Order of the Network Adapters
Change the order of network cards: On the Binding tab available from the Network application in Control Panel, select Choosing Protocol and change the order in which NICs are listed. Then restart the computer.
NOTE: The order should be the same for both nodes. Also note that method 2 is not as good as the first approach because the performance for node-to node communication will be affected.
