I'm running a SBS 2008 and a Windows server 2008R2 on a VMWare ESXi 4.1 host.
Every few days the SBS 2008 freezes and is unresponsive. AD, Exchange, DNS, DHCP are not working, but it is responding to PING. Remote Desktop tot the SBS 2008 is also not working.
The Windows server 2008R2 is still responding, but I can't login is a domain user because AD is not functioning.
Also thru the vSphere Client Console the SBS 2008 is not responding. A soft restart or shutdown is also not working. Only a hard shutdown and a restart will bring te server back online.
