So I have been looking for fixes for this but can't find anything so I thought I would post on here.
I work in a college and today we has some issues of some students not being able to access a website, this was something that was 100% not being blocked by our proxy and was effecting users as it is a CDN used for CSS assets for a government. First thing I checked was if the site was up, I pinged it and tested it on a test account and both were working.
After a long half hour of testing things, we took a look at the users accounts that were having issues and we found that the students were in different OU's as they joined the college in different years (thats how we segment them).
We tested this theory and were correct in saying if we move the students that had issues into a different year OU it worked for them.
My issue is now, what caused this. I have done gpresult on both of the accounts but as they both give about 3000 lines each.
So, my question is, is there any policy that could cause this issue? is there anything that I could do to get my self closer to the issue. If any more info is needed just ask.
