Problem still persists - have checked my firewall logs and there are no dropped packets on the ports. Must be something to do with it being a virtual machine.
Here's the VIPM error log, if that's of any use for you to troubleshoot. Some sort of generic error 42.

It's very frustrating not being able to debug this myself... Would you care to set up a replication on a Hyper-V virtual machine, and see whether you get the error and if so, why? Hyper-V comes with all windows installs anyway, it wouldn't take you long.
Edit: set up the replication on a non-networked VM. It connected fine. Seeing as it is not a firewall issue, could you suggest some further troubleshooting steps please?
