Vizioncore released vRanger Pro DPP 4.5 in late May. Since then I've had the opportunity to upgrade several clients to the new version. The performance enhancements have been super, and a couple of customers have seen their backup times cut in half – and this has been true even for one customer who is still running ESX 3.5.

A great review of the new features in version 4.5 can be found <a href="http://virtualization.info/en/news/2010/05/release-questvizioncore-vranger-pro-4-5-dpp.html">here</a>.

Even with all the bug fixes and performance enhancements a new error message has popped up for at least one customer since the upgrade. The error is:
<p style="padding-left: 30px;">"Message: An internal error occurred during execution, please contact Vizioncore support if the error persists. Error Message: There are currently no ports available for the status port monitor. Please reconfigure the range of ports available for status monitoring."</p>

My contact with Vizioncore Support revealed that this is a known issue, but it will be a couple of weeks before a fix is released. Rebooting the vRanger server corrects the problem but it seems to reoccur every few days.
