Virtual Machine IPs are Removed during VMware Restore

Hello, I am running NetBackup 7.5.0.4, VSphere 5.0. I restored a VM on 1 May to it's original location and was able to authenticate to the domain upon restore. Yesterday I restored another VM to an alternate location and attempted to logon and was unable to because the machine lost it's NIC settings during the restore. I then restored another VM to it's original location and was unable to authenticate to the domain because the NIC settings were set to a private IP during restore. I can't seem to find a trend. It leads me to wonder if NetBackup up capturing the vmx file so it can restore the machines settings. The only guidance I found on this pertains to VCB and we are using VStorage. Has anyone successfully resolved this issue.

When restoring are you powering on the VM and also restoring the NIC connections?

I do not select power on after restore.  I think that I am restoring the NIC connections I select the applicable NIC when restoring to an alternate location.  I'm not certain if this answers your question.

So your powering on manually? Are you doing SAN backup SAN restore?

Yes

What O/S are the VM's you are restoring?

Just wondering if it is caused by the MAC address needing to be changed after restoring Linux machines to alternate locations?

Mark, they are Windows 2008 R2.

Mark, I came across a thread in the VMware community  that suggested the same thing for Windows 2008 R2.  Someone suggested that windows thinks it has a new physical NIC because the MAC changes and therefore wipes the IP.  They suggested documenting the generatedAddresss form the .vmx prior to restore and edit the new .vmx upon restore.  I don't have permissions to these files so I was trying to ensure that nothing could be done from a NetBackup perspective.  I'm running a restore now to its original location.  I think I'm going wrong at the network connections menu.  I select the PROD PG-301 (see attached) as this is the network that the majority are on when I verify on the summary tab in VSphere.  I just noticed that there is a box for select all?

Using vmxnet3 as the VM nic hardware and Windows 2008 R2 then you need to follow this kB article to install a MS hotfix. http://kb.vmware.com/kb/1020078 Cloning or restoring a VM like this will enumerate a new Mac address nic and you lose IP config.
