I\'m using Collabnate Subversion Edge.
I\'m getting below error when trying to access URL http://localhost:3343/csvn.
Collbnate is set up on Windows Server 2008.
I had the same issue, CollabNet Subversion Edge version 4.0.4. In my case the problem was updating the JAVA_HOME from JDK 1.6 to JDK 1.7.
I finally resolved it changing the file: C:\PROGRA~1\csvn\svcwrapper\conf\wrapper.conf
I changed the value of the property: wrapper.java.command:java wrapper.java.command=C:/PROGRA~1/Java/jdk1.6.0_45/bin/java
So the csvn now runs with 1.6 as before. And it works again as a service automatically.
Good luck!!
