windows 2008 R2 64bit looses network share

[copymaster]

Hi
we are running a cluster with 4 physical servers.
We have several windows 2008 R2 64bit Termianlservers. The terminalservers get networkshares from a fileserver.
but sometimes one (not all) server looses one of the shares. Netzworking is ok, other shares that reside on the same fileserver are accessible.
i can reproduce this by using the tool "freefilesync" or "richcopy".

with the tools i try to copy files from one fileserver to another. That is done in a KVM WIndows 2008 R2 64bit machine. After a short time the progs are running there's an error saying:

networkshare is not accessible.

and by looking in computer, i see that the share is really not accesible. other shares work and the "missing" share is also accessible from another kvm machine.

I tried e1000 Networkcard and virtio networking (with the drivers from the iso) both with same results.
I also tried to apply the network tuning tips from kvm.

hi
pveversion -v says:

pve-manager: 1.9-24 (pve-manager/1.9/6542)
running kernel: 2.6.32-6-pve
proxmox-ve-2.6.32: 1.9-47
pve-kernel-2.6.32-6-pve: 2.6.32-48

And the virtio driver is from the cd virtio-win-0.1-15.iso
is version 60.62.102.2000 from 10.08.2011

I had the same issue with iSCSI drives.

In "my case" the most stable windows guests are a mix of virtio driver versions.
the most recent virtio NET and the old virtio Drive (version 5.0.<something>, it's the oldest ISO available).
Also tried all the original RedHat I$O drivers (incl. Beta), no luck .. for me, the virtio windows is a nightmare.

IDE and/or e1000 are stable, but slower.
