Solved the problem on my end. I don't know why it should matter, but I was using an E1000 network adapter on the VM's giving me this issue, I switched them to VMXNET 3 and have not seen the issue re-occur. This was almost a daily problem and it has not happened for the 8 days that I have been running the VMXNET 3 adapters. I know some of you are not using VMWare ESXI hosts, but for those that are, give this a shot! ESXI 5.1 Server 2012R2

First time poster here and this thread alone made it seem like a good idea to register. We are also having the problem with our Windows 2012 R2 Servers. I have servers running Windows 2012(not R2) and have not seen the problem recently but was most definitely having the issue months ago. The R2 Servers I just stood up are having the issue pretty much daily. We are running a full virtual infrastructure. ESXI 5+ on a mix of hardware. Dell servers, HP servers, extreme networks switches, you name it, we have it someplace. I feel we can all pretty much agree this is an issue on the software end of things. As a work around, I am letting KACE restart the "Server" service every 30 minutes to prevent any down time. That still creates about 15-20 seconds of offline sharing though and is really not an acceptable option. Looking through the logs, I do not see anything going down and the "Server" service has always been running when my shares were not accessible. I can't say I have seen this problem on shares that are not also hosting printers. That said, I have no technical data to back that up. Just what I noticed. I read some info about disabling the IIS roles. I don't have any of that installed on my file servers so that can't be it.
