A join command that specifies the domain controller during the join is failing. The join command may look like this.
# /opt/quest/bin/vastool -u admin join domain.com dc.domain.com
The error would then state something like the below and the name has been verified.
ERROR: Server "dc.domain.com" does not match one of the provided names.
Please re-run with the server's full-qualified name (or let QAS choose).
Ensure that the join command matches the case of the domain controller exactly. This includes mixed case names as well.
For a domain controller called Example1 the command should resemble this;
# /opt/quest/bin/vastool -u admin join domain.com Example1.domain.com
This has been logged as Defect # 380841 and will be resolved in the next Maintenance release that will be a revision higher than 4.1.0-21140
