Server with 2008 drops network connection

I have a new Dell R610 server with Windows Server 2008 64bit.  It has 4 gigabit network cards.  One card is connected to a new Cisco 2960G switch on our existing subnet.  Two cards are connected to the same switch in a different group of ports on a different subnet.  Those two connections are for the server to connect to an iSCSI SAN on the new subnet.  The server logs in to our primary domain.  Other servers and workstations on the domain can see the new server.  When I am on the new server, browsing the network is very slow, but it eventually sees all the computers.  The server is running SQL 2008 standard.  Workstations on the network that access SQL databases on the SAN are periodically dropped and have to reconnect to the database they are working in.  Remote desktop sessions to the server are eventually dropped.  I set up a continuos ping of the server and most replies are <1ms or =1ms.  About every 4-5 minutes there is one of from 2 to 6ms.  I tried connecting the server to one of our existing switches and have the same problem.  We tried the remaining network card and a new cable with the same results.

Any suggestions would be appreciated.

Go into your Network Connections click Advance Settings check your binding order to make sure your primary NIC is listed first.

On your iSCSI cards make sure you have unchecked the Register this connection with DNS on the network card properties

Thanks dariusq for your suggestions.  I am going to make your changes after hours.  I did discover something today.  The DMZ port on our firewall is set to the same subnet as the iSCSI cards so we probably have a conflict.  We are going to get that changed, too.  I will wait until be do this before deciding on points.

I made the suggested changes and they helped.  We had the ip address for the iSCSI network changed and that was the final solution.  Thanks for the help.
