RS Integrated With MOSS - Internal Error - AdjustTokenPrivileges

I'm running MOSS 2007 Enterprise, SQL 2005 SP2, RS integrated with MOSS and have a number of reports deployed to a Reports Library in MOSS. 3 out of 10 times I run a report I get a error message stating that 'An internal error occured on the report server.' Just hitting Apply on the parameter panel will fix the problem and render the report as expected.



Previous entries to the forum about this error hints at an error that supposedly was fixed in SP2; since I'm running SP2 something else must be the problem.



Any insight to what might cause the problem ?



Regards,

Trond
