My client has a new PowerEdge T320. With VMWare 5.1 installed running Windows SBS 2011. The problem is that all of a sudden the server seems to go offline. Then within a couple of minutes it will come back online. This will occur many times over the day. When this happens the workstations, of course, cannot access any of the network resources including internet access. However, there is internet to the workstations as I can still access them remotely via my Citrix.
What I have already done:
- Switched ports on the back of the server
- New cable
- New switch
- Just downloaded some Windows updates to see if that will help
It does seem to occur when someone first logs on in the morning. I can watch it all evening and no apparent issues, but as soon as someone comes in I can expect a call. But at the same time it's not a defining thing it's so random during the day.
