random 404 pages when accessing CRM

This question is answered

This issue pertains to CRM 2011 using ADFS on a Windows 2008 server.

After resolving some issues with having multiple bindings to the CRM website, I am now faced with the problem that after a certain interval, the user receives a 404 - File or Directory not found page when trying to access the CRM page. It's not until the user closes all browser windows and re-opens Internet Explorer that they are able to access the page again until the next time the page errors out.

  • Yes and no. It is an official bug that has been acknowledged by Microsoft after months of having an open case with them. It is an issue where the session times out and the ADFS token is rendered useless, until refreshed. The workaround has been to append the Org name to the end of your URL e.g. https://crm.domain.com/Orgname. I received a tentative hotfix release targeted for Rollup 10 :fingers crossed:

  • Hi Gus,

    Thanks for your reply. I have already increased the ADFS Token Timeout to the maximum value. I don't believe this is the issue as I am not receiving any prompts about my session expiring. What is interesting is that the original page that was open will continue to work once the 404 page is received. It is only subsequent pages that are opened that get the 404. And once the original page is refreshed or all browsers are closed and reopened, then the page can be accessed again.

  • That's weird...are there any other time outs related to IIS that could be causing this issue?

  • Yeah, I'm thinking it is an IIS issue but only related to that site, as my Sharepoint site is also hosted on that same box but does not experience the problem. I have a case open with MS already but no one can seem to figure it out. That's why I thought I'd try my luck here.

  • Did you ever get this figured out? I am also having the same exact issue.

    Thanks
