I was trying to edit some of rdl resports on one server and get this kind of error :
he permissions granted to user ‘NT AUTHORITY\ANONYMOUS LOGON’ are insufficient for performing this operation. —> Microsoft.ReportingServices.Diagnostics.Utilities.AccessDeniedException: The permissions granted to user ‘NT AUTHORITY\ANONYMOUS LOGON’ are insufficient for performing this operation.
when I googled this error it gets me lots of soultions from the internet however none of them couldn’t fix my problem or the soultion was not fitting exacly to my problem in my opinion.
I went to Central Administration of my SharePoint and try workaround with it and this was the key to fix my problem.
Open your “Manage Web Applications” in “CA” and then click on your Web App where problem exist, then choose the “Authentication Providers”
and choose the “Zone” which you “Web App” is using
uncheck the box of the “anonumous access” setting and you done !
if others methods from stackoverflow or any services dosent seems to help try above steps. Hope it helps.
