Title:
  Mounting a share in fstab fails with BAD_NETWORK_NAME

Status in cifs-utils package in Ubuntu:
  Expired

Bug description:
  The following command works:
  mount -t cifs //192.168.1.200/Drive_E /mnt/server_e -o credentials=/root/.smbcredentials_server 

  The following fstab entry fails:
  //server/Server_E /mnt/server_e   cifs   uid=0,credentials=/root/.smbcredentials_server,file_mode=0755,dir_mode=0755,vers=2.1,sec=ntlmssp  0  0

  There is an entry in hosts for server. It also fails with //192.168.1.200/Server_E
  Sometimes it says:
  No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount.
  [ 2079.955734] CIFS VFS:  BAD_NETWORK_NAME: \\192.168.1.200\Server_E
  CIFS VFS: cifs_mount failed w/return code = -2

  trying vers=1.0 and vers=3.0 makes no difference.

  There is no documentations of CIFS VFS error codes
  There is no documentation of how to specify the SMB dialect.
  People appear to have been having trouble with these things for at least the past 10 years.

  I never had a problem with this on debian.
