I'm running a Windows 2003 SBS server with Acronis True Image Echo Server. I'm getting this error all the time ' Scheduler unable to run the task with GUID.... because of the 1326 (Logon failure: unknown user name or bad password). If I do a complete back up I do not get the error. If I do a dif. or incr. I always get the error and I'm not sure what to do about that issue. My copy is build 8,018 and I'm not able to find any updates. Any ideas?
