Hi everybody,

My setup: TP-Link Switch SG1008D connected to: 1x 1000kbit NIC on a Hyper-V Core-Server 2012, 1x 1000kbit NIC on my Desktop-PC (Win7 64bit), 1x 100mbit fritzbox 7170 (Internet).

I'm getting Gigabit between the Hypercore and Desktop with data-transferrates at ~50MB/sec, likekly because I'm still using SATA-HDD, thus about 450kbit/s.

This is my problem:
1) I'm running a Windows SQL 2005 Database on the Server-Core. When I connect to the Database with my Desktop I'm getting persistant connection losses resulting in the programm crashing/not responding.

2) I'm doing RDP between the Desktop and the virtual-machine on the Hyper-V Core with connection losses all the time

So far, I've tried to turned off AVAST Virus-Scanner, without results.
Using an older TP-Link SF1005 100mbit Switch all is fine.

I'm lost, what may I do to resolve the problem?
