MSDTC error while using Transactionscope

In one of my project while writing a client application in VB.NET I had to make a call to two different databases on different servers and in case of error encountered both the transaction had to roll back. I used transactionscope to achieve this. I could use this since the database server is SQL 2008. Transactionscope ( a very cool thing) can be used on in SQL 2005 or higher. However I was running into the following error whenever while trying to open connection2 ( second conection ).

Network access for Distributed Transaction Manager (MSDTC) has been disabled. Please enable DTC for network access in the security configuration for MSDTC using the Component Services Administrative tool.



Here is a snippet of my code (in VB.NET)


While debugging through the code, it thre error as soon as it was trying to open the oConn2 ( server2)
I checked in the database server if DTC was enabled. It was. What I had missed was the MSDTC had to be configured in the client server as well. Once the MSDTC was configured on the client server Viola it worked like a charm.
