Authentication problem - Urgent

During the development of the project I used windows authentication on IIS
and everything was working perfectly. But the user must access the reports
through a web application, so I changed the security to anonymous and set the
rights on RS for the anonymous user and since then, the server has crashed in
a random way (rsProcessingError). If I reapply the security the same thing
happens. Does anyone have any ideas?Possibly - we are using a custom built proxy, and in order to use
System.Net.CredentialCache.DefaultCredentials I had to allow anon access.
When deploying it broke [b/c IUSR_machinename didn't have the correct
priv's]. There is a post on how to allow anon access & be able to deploy
reports [titled "does anonymous access have to be disabled in iis?",
8/10/2004] on how to set it up. Note you do it in reporting services, not
iis. Maybe this will get you on the right path.
Good luck,

I already tried to put anonymous user as content manager on RS and PowerUser
on the server. But the problem is the same.The report crashes once
every one hundred times with the same parameters by URL and the same error
message.
The processing of group expression for the table 'table1' cannot be
performed. The comparison failed. Please check the data type returned by
group expression.
