a virtual server is losing connectivity

Source: microsoft.public.virtualserver
Sent: 01/11/2005

Message:

We just built a virutal server host (static ip) with 2 virutual servers (each
using DHCP). The virtual server host has one Intel PRO/1000 XT network
adapter. Every so often one of the virtual servers loses all network
connectivity. The connectivity will temporarily return if I reboot the
virtual server or if a disable then enable the virtual network adapter (from
the Windows 2000 virtual server).

I have had this happen before on VMWare's ESX server and the solution was to
change the virtual network adapter. Since MSVS only seems to use the Intel
21140-based FastEthernet (generic) adapter, I don't know of another choice.
Anything here sound familiar? Any known fix? Is there a way to emulate a
different virtual network adapter?

The Virtual Server's DHCP server capability is disabled. The virtual server
is just picking up it's DHCP info from our company's internet DHCP server.

Thanks!

Have you disabled TCP/IP offloading features on the physical network
adapter?

No, I didn't. I'll keep that in mind if it crops up again. What I ended up
doing was removing that virtual server, creating a new one, identical to the
old, using the old existing virtual disks, and the problem went away.
Disappointed I couldn't find the problem but oh well, the customer's happy so
I'm happy.

Pardon my ignorance, but just what (specific) features fall under the
"offloading" feature set.

My Intel board lists Large Send and TCP Segmentation. In my hardward
settings I can find a "Large Send" entry, but nothing about TCP
Segmentation.

Any specific features and settings I should be looking for?

Hi Todd,

a update to the latest nic drivers from Marvel solved the same problems at
my server.

Best regards,
Boris Wehrle
