In 6.1 I had backup and archive backups configured to go to a CIFS share \\server\backups\LEM
Ever since I upgraded to 6.2 this fails if I change the path to \\server\backups I can connect
It does not appear to like connecting to anything other than the root share, this all worked just fine in 6.1
Have you opened a ticket with Support on this yet? If NTLMv2 is somehow broken in 6.2, we'd need the Support history so the issue can be diagnosed and sent to our developers for resolution.
