Application CATIA changes randomly share access via DFS
Applies to
- ONTAP 9
- Computer-aided three-dimensional interactive application (CATIA)
- DFS (Distributed File System)
- CIFS
Issue
- CATIA is accessing shares via DFS and is changing server access randomly
- DFS is setup for location access based on costs, but it's suddenly changed
- TCP Dump shows errors like
'STATUS_OBJECT_NAME_NOT_FOUND' - ONTAP shows a lot of anonymous session logins generated by CATIA:
::*> cifs session show -vserver <vserver> -windows-user "NT AUTHORITY\ANONYMOUS LOGON"
Node: <Node>
Vserver: <Vserver>
Connection Session Open Idle Connection
ID ID Workstation Windows User Files Time Count
