Hello,
We have just built 8 new Virtual Machines which we have added into our existing farm environment.
The Machines are running Server 2008 R2 and have one NIC, In the existing layout we have 6 Servers that have two NIC's one on a 10 range and one on a 172 range, these work fine, however the new servers disconnect from the Farm after a random amount of time disconnecting any users who are connected, the session remains open but the user has to reconnect.
The new Machines only run on the 172 range and the only slight indication of a problem I can see is that in the event logs we are being told that the machine has successfully left the farm and then 2 seconds later it has rejoined it.
We dont have any time restrictions set on the machines to disconnect a user after a certain period but the existing machines with the 2 NICs say the same thing about leaving and joining the farm but only on the 172 range.
If anyone has any thoughts on what it might be that would be great.
Thanks
