Hi,
a big problem with our report server has appeared suddenly.
We are running the SQL Server 2008 R2 with a Report Server. But a .
I can connect to the Report Server Website and I can choose a report. But if I run the report, it will load endless without timeout message or other error messages.
I looked in the Report Server Log and find out this confusing error messages:
...

The last think I have done, is to grant a new user access to the report server website (by using the site options) and to the root folder (by using the folder options on ws).
But the error must not relate to the new user. The server was not touched for several days before.
Could you plz help me? I have no idea what to do.
Googling the whole day to find a solution without success
