Everything works fine for most accounts 100% of the time but here and there some users who are able to access a subsite fine one day are greeted with a standard 404 the next. This can last for an hour or two days, it's really inconsistent.
I check the iis logs and it says the status is also a 404 for these requests, nothing else looks unusual. Sharepoint logs have nothing for the timestamps either.
Correct me if I am wrong but if it was a permission issue an access denied message would be shown.
It is not the individual computer because when a user is having this problem and I can log in with their account and I also get the 404 error although I am on the exact site with another account in another browser at exactly the same time, and it works perfect.
Any suggestions would be greatly appreciated, I've done a fair amount of searching but can not find a similar situation or help anywhere.
It was a permission issue, I had figured this out awhile back but basically a few accounts were not setup properly and could not load a fresh copy of the page, when someone else would hit it they would be able to view the cached page fine. Error was never thrown as a permission issue or access denied anywhere but this is what fixed the problem.
