I am having very intermittently dropouts from one of my workstations, which is the only PC in my setup of Macs. The dropouts only occur on the PC. I'm also running the latest version of VE Pro.

The dropouts are a fraction of a second and affect the audio from all the VE Pro instances on that PC, while the audio from the Macs continue without interruption. The VE Pro instances all have multiple audio outputs enabled and I am bringing into the DAW on the Mac a number of audio streams from the PC.

Capacity of the CPU, hard drives, and the network connection are all more than sufficient, so no performance related issues that I can detect.

Looking at the network performance meters in the Windows Task Manager, I do see a short drop when the dropouts occur, either because something is interrupting the network connection temporarily, or the VE Pro Server is having some sort of issue.

What would be the best approach to further diagnose the issue?

a dynamic, or changing IP address(es) could cause this. If you haven't fixed the IP manually, do that.

Thanks for helping to diagnose the issue. The IP address is always the first thing that is changed when a new workstation is introduced in the studio. Dynamic IP addresses can wreak havoc. It's always best to do this from the router or DHCP server rather than the individual workstation.

In this case, that doesn't seem to be the issue, although it's entirely possible that some system or gadget in the network is trying to grab that IP address. I'll check on that, just to be sure.

I still feel that something else is at the root of this.

"DHCP server rather than the individual workstation." you've described a part of your network that behaves differently. Not 'rather than', it has to be static at all points. "The dropouts only occur on the PC" - have you not dealt with the DHCP on that machine then?

Agreed. All workstations in the network have static IP addresses, which are defined by the DHCP server and tied to their respective MAC addresses. We should be good on that part.

The workstations themselves are set up to get their IP addresses assigned by the DHCP server based on their MAC addresses registered with the DHCP server. 

My understanding is that this should ensure that no IP address changes occur. Perhaps I am mistaken.

At any rate, checking on the IP addresses of the workstations, they don't seem to be changing. From that I take it that all is set up properly.

it's been a couple of years since I researched this but I don't think the server is ensuring that.

my assumption is the opposite of yours, I believe that 'the client requires a static IP'. this is not my field so someone should correct me if that is bad.

My browser recalled my searches easily enough: the website "Windows Server" for instance has this *answer* [to "do I need to make my computer and server both
Static IP Addresses or just one of them. Or are both IP Addresses the same when one change the other will too?"
]

:

You treat each OS instance as separate systems.  So, address
them separately, or if you set them to DHCP, they will receive unique addresses.

I wouldn't assume that OSX works as a "Windows Server", which would I think ensure the static address at the other end.

 If you're sure, who am I to say, but this can't hurt.

I know I'm drudging up a dead thread, but I'm having the same problem. Did you ever resolve this?

I'm using EW Hollywood Strings on my PC, nothing else is running, very little of the memory is being used, very little CPU, but I get the dropouts.

On the Mac (DAW) I can run Hollywood Brass and Woodwinds with now problem, all instruments at once, so it doesn't seem to be on the Mac end or the PC. Definitely seems network related somehow.

Any suggestions on how to fix this? I'm getting the exact same thing mass dropouts affecting all channels for a brief half a second.
