DL380G5 - network name no longer available

[John Has]

Hi all,

We have 2 new DL380G5 machines - Win2k3/R2/SP2 which we have just added to our network. Support Pack 7.91 is installed. NICs are running as a Load balancing Team into our ProCurve 5308 Switch (latest firmware). When copying large files to the machine over a WAN connection the file transfer starts and then fails with "network name no longer available".
We have had some intermittenet connectivity between the two G5's as well (one is a SQL Server, one a SharePoint box)

However copy files from the WAN connected server to any of our other earlier generation DL380's works absolutely fine.

So it seems that the network cards 'time out' although pinging works fine during this......
Both machines exhibit the same issue - they were not bought together and so I presume not from the same faulty batch!

Any ideas welcome! John
