Broadcom NICs seem to have a lot of issue related to checksum offload and TCP chimney stuff. Perhaps the x64 Broadcom driver has an issue that the x86 driver doesn't
I've check the VMWare forums - they are quite good.

The VM nics aren't mapped to any specific 'real' nics, they all just use bridged networking using standard defaults. The issue ONLY arises if we move a 32bit made VM to a 64 bit platform. 32 to 32 works fine.

I had a bunch of issues when I had a host plugged into a 100mbps switch. There's plenty of posts on the VMWare forums about that. Cheers Len From: Michael B.

I'd go through the steps around disabling TOE that have come up so much on this list. I'd also make sure that your host NICs are plugged into a gigabyte switch.

Anything I can easily do ? I thought the whole idea of a VM (particularly the VMWare ones) was that you can download one and run it on any platform running the VM software and it won't moan about the underlying hardware...or have I got that wrong ? From: Joseph L. Casale [mailto:[EMAIL PROTECTED] Sent: 15 February 2008 19:16 To: NT System Admin Issues Subject: RE: 32bit VMs on 64bit platforms Actually it sort of is a vmware *server* issue:) Unlike ESX, server doesn't provide a consistent view of hardware to the vm when you move it to another computer, you *may* encounter some issues as it is exactly like taking the HD out of computer from Vendor A and plugging it into Vendor B's platform. As you can imagine, YMMV doing that. We all know it *usually* works, but... What kind of NICS in the new server? Do you have tcpip.sys patched to a recent version?

I doubt it's a VMware issue, even though I have no experience with it. Have you disabled TCP Chimney on the new server? Regards, Michael B.

Our VM server here maxed out its ram limit, so we have a nice new 64bit server with 6GB and Win2k3 64bit. It's running VMWare Server. Everytime we move the VM's over, the VM's fire up and appear to run fine, but we have all kinds of problems with networking on them. Most of them run Linux based web sites, and while we can use the VM, viewing the websites that the VM hosts takes forever (that's when it's working at all). I've even downloaded VM appliances from various sites and those fire up, but again, trying to connect to the websites on them or any other IP based service seems amazingly hard work. Should this be the case ? Olly ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
