Answer 1

1. Sometimes it may be normal behaviour. Partly interrupted ping stream need not be a sign of something wrong.
2. There are more parameters that may play the role, namely the client. SMB version mismatch, autotuning and similar problems may cause irregularities. Also another computer on the same network may cause problem. (see 5)
3. Are there any errors in Event logs? Is there any unresolved problem in Device manager (wrong NIC driver)?
4. Use performance monitor to exclude problem with longer queues for NIC.
5. Use network monitor for catching and analyzing network traffic.
