Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <html> Do you want to continue running scripts on this page?
OrSystem.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception.
System.ComponentModel.Win32Exception: The target principal name is incorrect
To solve it, register the following SPNs:
- setspn -a http/<CrmApplicationServerName> <CrmAppPoolServiceUserAccount> (E.g. setspn -a http/devcrmserver domain\crmappservice)
- setspn -a http/<CrmApplicationServer FQDN> <CrmAppPoolServiceUserAccount> (E.g. setspn -a http/ devcrmserver.domainname.com domain\crmappservice)
NOTE: If you have multiple CRM Application servers, you would need to do this for each server.
NOTE: If after you make this change, your users start complaining they can no longer log into CRM, make the following changes on your CRM server ApplicationHost.config file:
1. Open the ApplicationHost.config file in a text editor.By default, this file is located at %windir%\system32\inetsrv\config\ (Crm server).
For all folders under the Default Web Site location path, set the value of the WindowsAuthentication element and the useAppPoolCredentials attribute to true.
For example:
<system.webServer>
<security>
<authentication>
<windowsAuthentication enabled="true" useAppPoolCredentials="true" />
</authentication>
</security>
</system.webServer>
Try run any of customized reports again, they should work like other any out-of-the-box reports.
2. Run an iisreset
