Yes, I was escalated to a developer in Russia and after an hour or so with him the issue is resolved. Yesterday I went back and forth with first level support and they were having me try things that I'm always asked to do in previous incidents for this issue. I probably have a few hours invested into it this time. I'm frustrated, but I appreciate your help foggy in getting me escalated, so thank you.
For anyone else coming across this, there are two different issues with SureBackup and domain controllers not coming up. One has to do with VSS and one has to do with some registry issues which are ultimately a Windows OS issue although VEEAM can get around it with a dll change. The VSS issue was fixed in patch/update 2 for v8. The other issue was not. For my scenario, the second issue with the registry has always been the issue. This is due to our VEEAM server being Windows 2008 R2 and the domain controller being Windows 2012 R2. Development literally created the dll I needed while on the phone and he sent it to me and now I'm good. If anyone on v8 with patch/update 2 has the same issue I have, call support and reference my case number to get the dll that fixes this. The case number is 00911043. Even if you are on older versions, this issue has been around for quite some time and I would mention this case.
I hope this post is helpful to others. I appreciate the answers that VEEAM employees give in these forums and I appreciate the attention that they get me with support. I think VEEAM makes a superior product and I would never use anything else for our backups. That said, I am really disappointed with this particular issue and all the time and frustration I've gone through over the last year. Please make sure this issue is addressed in the next update so I don't have to go through this a 5th time.
