Hello there,
Was hoping to get some help with an issue:
Currently in our testing environment, one IIS site (out of two) intermittently asks for credentials.
Our monitoring responds with 401 errors (believe due to login prompt) – shown below: (shortened)
GET / – 80 – Microsoft+Monitoring+Agent+7.1.10184.0 – 401 2 5 0
Both sites are configured for SSO, the other site works fine all the time, even while the affected site is having issues.
This issue is intermittent – occurred 2 days out of 7 this week.
We currently have a workaround of restarting only the affected site, which then allows users to access via SSO,
and we even have an automated task for this.
However I would still like to resolve the root issues itself. Event gaining a greater understanding of how a user SSO request can be transformed into needing credentials, and what common causes of this may be. Any help is greatly Appreciated.
Additional info:
-IIS version 6.2 used
-Windows server 2012 R2 used
