Troubleshooting across Domain
When connection between ” NVR domain controller” and another NVR (child) in its domain is broken, the
system has to have the ability to continue its work and do the synchronization later.
In case of a
“broken connection”
between Domain controller and a remote site such as site “A”:
1.
If
o
The whole situation is looked at from remote site “A” standpoint,
o
User (e.g. site ”A”) is still allowed to change its own site
⇒
NVR will go into “Synchronization failed” mode and will not update information across
domain.
Only Domain Controller can bring site “A” to “Normal” mode. Click on
“Import”
button in
order to bring site ”A” into “Normal” mode (Fig. 44.)
2.
If
o
The whole situation is looked at from “Domain Controller” standpoint,
9
Either, site “A” (Remote NVR) is in “Synchronization failed” mode
9
Or a “broken connection” between “domain controller” and site “A” has occurred
⇒
No update will be allowed to site “A".
To synchronize Domain database with the remote database click on
“Import”
button for
appropriate Remote Site (see “
Import
” button on Fig. 44.).
