Running more than one VMware guest at the same time on the system results in the same VMware guest network failures again. I have to revoke my former comment!

I also had some of the other issues mentioned. Disabling TOE by removing the TOE2 widget cured the problem. I would point out that it appears at first to be possible to disable TOE in the BIOS, but in fact only removing the widget works.

Environment: Dell Poweredge 2970 (with Broadcom Netextreme II and TOE-Adapter), CentOS 5.0 / CentOS / SLES 10 SP 1 as Host-OSes, VMware Server 1.0.4 for virtualisation. WinXP Pro, Win 2000 Server, Win 2003 Server as VMware Guest OSes. Initial problem: In irregular periods after a couple of hours the network connection to the VMware-guests (bridged network mode) broke down for about 1 minute - usually 2 or 3 times a day. Unsuccessful approach: Changing network devices - I deactivated the onboard NICs and installed an Intel Pro 1000/PT adapter. The problem stayed. Solution: In the first place: pulling the TOE 2 adapter and as a second important thing: Setting VMware Server in the Host/Settings/Memory Setup to "Fit all virtual machine memory into reserved host RAM" After that no additional breakdowns were measured so far.

This was driving me nuts. I can verify that it worked on my PowerEdge 2900. Pull the plug, restart and the VMWare guest OS and server host OS (2003 R2 x64) can see each other's shares. Thank you!
