We have NT 4.0, Svc Pack 4 with Exchange 5.5, Svc Pack 3.
Backup Exec V 7.3 Build 2575
Exchange Agent installed.

We're having trouble backing up open files as well as Exchange
Store files ie-priv.edb and pub.edb.

Upgrade to Build 2575 went smoothly, appeared everything worked.

We don't have the vncsnapshot service and unsure how to install it (no
to do so is available) and, therefore; the OFO is unavailable.

Our question: How do we install the vncsnapshot service and OFO?
