We have a ESX VMware cluster running 5 ESX hosts. The host are in a HA Cluster thats been working fine for quite a while. I recently installed a new VM guest running Windows 2003 Standard Edition. Then installed SQL 2005 Enterprise Edition so we can develope SQL instance databases.

Every few weeks we lose connectivity to this vm and cannot RDP to it or ping it. If I restart the guest OS' its fine for seemly a few more weeks. When I check the event logs on the Windows VM they are clean and no indications that Windows lost any network connectivity.

This is the only VM we have this issue with.

The server was a fresh installation, not deployed from one of our templates.

Thanks
