Snap Deploy 3 (build 3329) deployment failure

Hi,

I am currently using the trial of Snap Deploy 3 (build 3329) and although the product fits what we are looking for as a deployment solution, I am having problems deploying an image.

I have installed all required server components without issue.
I have created a master image of a Dell GX520 without issue.

When trying to use the Snap Deploy Agent I can see that the machine has connected to the network but when attempting to push out the image I receive the following error messages -
Error Code 1 - Host '........' failed to deploy.
Error Code 13 - Operation was cancelled.
Error Code 3,407,876 - Specified session ID was not found.
Error Code 0 - Session manager: Session 0 to remove not found ...

Since I am using the trial with hopes to buying the full product, I would like to be able to fix this issue.

I have been able to deploy an image using the Standalone utility and this has worked fine (except for the autosid issue others have reported).

Update - Although changing from Multi to Unicast made no difference, I've created a template with almost no customisation and this has worked. There appears to be a setting that is causing my issue.
I will report back if I find what the cause might be.
