Is there enough disk space on the server where you download the updates ?.
PRAJWAL Thank you so much. I can't tell you how many guides i've used of yours truly appreciative of your vast knowledge. So to answer your question yes plenty of disk space.
So onto my next issue i had uninstalled WSUS and attempted to start from scratch. i can install the WSUS roll not problem but no matter what i've tried always fails the post installation task. I have been at it for 3 days now and super frustrated. any help would be greatly appreciated.
Here is the entries from my post installation task log:
