A client attempted to access the server using SMB1 and was rejected because SMB1 file sharing support is disabled or has been uninstalled.

Guidance:

An administrator has disabled or uninstalled server support for SMB1. Clients running Windows XP / Windows Server 2003 R2 and earlier will not be able to access this server. Clients running Windows Vista / Windows Server 2008 and later no longer require SMB1. To determine which clients are attempting to access this server using SMB1, use the Windows PowerShell cmdlet Set-SmbServerConfiguration to enable SMB1 access auditing.
