Hudson cannot launch slave - hudson-slave.exe not being copied

Question

I am trying to add a node to my Hudson master.

The node runs Windows Server 2008 Enterprise edition and it has Java, Ant and .NET installed on it.

The connection log of that machine shows this output and is never able to connect.

Connecting to machine01 
Checking if Java exists
java full version "1.6.0_25-b06"
Copying slave.jar
Starting the service
Connecting to machine01

Copying slave.jar

The message keeps on repeating and never connects.

Upon further investigation, I see that the "Hudson Slave at <FS Root>" service is registered, but the "hudson-slave.exe" in the FS root is not there. It means that this .exe file is not copied onto the slave at all. I have checked the entire hudson.war, but no exe file exists in it - may be it is getting created? Only slave.jar is being copied.

I wonder why no error is reported and master keeps trying. Can any one suggest a solution for this?
