I'm using Symantec Corp Client v10.012 in my domain. When i audit my network for threats using "Audit Network" utility, i got messages in type column like; Login error: Logon Failure: The target account name is incorrect. (1396). My question is this that whether symantec provide this type of Labels List. If yes then how can we take it and if no then how can we understand it.

Logon failure: the target account name is incorrect" error when promoting domain controllers or creating replicas
