Have your Reporting Services 2005 reports started failing recently with the error message?

 

Logon failed. (rsLogonFailed)

Logon failure: unknown user name or bad password. (Exception from HRESULT: 0x8007052E)

 

Check your Unattended Execution Account (UEA).  Is it a domain user? 

 

If so, check to see if the domain user's password has changed.  Has someone intentionally changed that domain user’s password?  Or, do you have a password expire policy in your network?

 

I run into this issue about once every so many days because our password policy enforces a password change every so many days and I use my account as the UAE.  Once you update the password (via the Reporting Services Configuration Manager), the login failure should disappear.
