Answer questions zanate4019

Yes, nothing really useful

Application '/LM/W3SVC/2/ROOT' with physical root 'D:\Program Files\ARA Development\Box Workflow G3' failed to load clr and managed application. CLR worker thread exited prematurely

Since it was also mentioned in the ancm log, I didnt mention it.

Side note: The same application has been deployed on a WIndows 2008 R2 server and is working fine.
