I everyone,
I know this is not a support site (per say) but I want to ask a “General Question” to see if anyone else has come across a particularly vexing issue I have with a site……………………..
At random times during the day users will be forced to re-authenticate if they are already logged in or as they log in they all get the generic log in screen poppi up three times then they get a blank screen.
In my experience this has always been simple change in the browser settings & yet despite reassurances from the on-site technical team that ALL browser are configured correctly there are still many occasions where users are being prompted to login & the credentials are being rejected & the user gets a blank screen.
I’m fairly sure it’s actually a network issue within the company, or an Active Directory Issue but I am being constantly told by an increasingly irate IT Manager that it has to be SharePoint.
Has anyone else ever had this experience, is there a default timeout for authentication to AD that I don’t know about?
Any ideas of pointers would be greatly appreciated because I am all Googled out of this issue now 🙁

Hi Mark,
It can be any time, at login or navigating sites & lists, the site can go days without an issue & then all of a sudden there will be a day (seems random) when the issue happens at random times. I’ve monitored the server farm & can’t see anything that could be causing this other than a crawl but then this isn’t hammering the CPU or processor all I would say is that the network cards appear to be getting a hammering.
The network has load balancing & multi split network segments with firewalls everywhere between segments & I am convinced that somewhere is all this soup there is something not working or blocking traffic.
The browsers are a concern, I don’t think ALL have been configured correctly but on the machines I look at the Internet Options is restricted & only the Techies can get access.
As I see it, because access to “un-restricted” content is not affect SP is working A OK, its the randomness of the issue when authentication with AD is required. Is there a default time out for authentication with AD?
BTW: SharePoint 2010 (running as 2007)
