Hi Mike, . Is this for CM07 or CM12
. What version of SQL are you running? . Where is SQL ad SSRS are they on the same server? . Is this for all reports or just some reports? . For how long does this problem exist?

(rsProcessingAborted) * Cannot impersonate user for data source 'AutoGen__5C6358F2_4BB6_4a1b_A16E_8D96795D8602_'. (rsErrorImpersonatingUser) * Log on failed. Ensure the user name and password are correct. (rsLogonFailed) For more information about this error navigate to the report server on the local server machine, or enable remote errors I checked permissions, they are fine. I even tried this fix, no luck. http://waveformation.com/2011/03/31/error-deploying-lync-2010-monitoring-rep orts/ The reports run fine at times, then a little later I get the error. Ideas?
