CRM 4.0 server 401.5 errors
We have a test environment that has been running CRM 4 on server 2008 for a couple of months with no problem.
Since a recent restart of the server access to CRM 4 has been denied . when attempting to connect to the web page ftom s client or the sserver you are prompted for kigin credentials and then it fails with 401.5 error got .5 from the log file
According to http://support.microsoft.com/kb/907273
HTTP 401.5: Denied by custom ISAPI/CGI Web application
An ISAPI extension or CGI application denied the request.
Identify which ISAPI extension or CGI application denied the request, and contact the developer or vendor to determine a solution.
All the services are running , I have removed and reinstalled the IIS role and this has had no effect. I have given everyone permissions to INETPUB directory . Next step contact developer ?
How do I find out which account the app is running with to try and rectify it if that is the problem ?
Any help would be appreciated
