SQL 2012 SP2 virtual name

Hi,

Background

Windows 2012 R2 and SQL 2012 SP2 2 nodes cluster with Quorum, MSDTC and multiple SQL instances

Node1 - 192.168.1.1 HeartBeat 10.0.0.1

Node2 - 192.168.1.2 HeartBeat 10.0.0.2

vClustername  - 192.168.1.3

vSQLname1\Instance1 - 192.168.1.4

vSLQname2\Instance2 - 192.168.1.5

Ping all names included virtual names - no issue.

\\node1\c$, \\node1\d$, \\node1\e$ and etc - all no issue.

But \\vSQLname1\c$ \\\\vSQLname1\d$, \\vSQLname1\e$ and etc - all failed (understand that it is by design).

Question

1. Do I need to add MSDTC resources to vSQLinstance1 and vSQLinstance2?

2. How to configure application to communicate \\vSQLname\instance1? As it is unable to map \\vSQLname\e.

Please advice.  Thanks.
