We have a Windows XP client ( TSM version 5.1.0.1 ) backing up to
our AIX TSM server ( TSM version 5.1.8.0 ).

It is initiated via the GUI supposedly to backup the whole C: drive but
the 'Last Backup Start' and 'Last Backup Completion' times are not being
updated on the server. It appears to be performing backups as seen in the
activity log.

The user whose machine this is has sent me the error log and it contains an
error at the time the backup session is ending :

2004.05.11 13:50:17 GetHostnameOrNumber(): gethostbyname(): errno = 11001.
2004.05.11 13:50:17 TcpOpen: Could not resolve host name.
2004.05.11 13:50:17 sessOpen: Failure in communications open call. rc: -53
2004.05.11 13:50:17 ANS1029E Communications have been dropped.

Could this be a consequence of being behind a Cisco PIX firewall ?
Why does it need to resolve a hostname in any case ?
Our network team have monitored the firewall and there do appear to be
some timeouts occurring after 30 mins ( the TSM server timeout is set to
10 mins ).

Has anyone else seen anything like this ?
