With the ending of 2003 server support, I upgraded most of our 2003 servers to 2008. These were all 32 bit VMWare virtual machines. After upgrading to 2008 32 bit (non-R2) and applying all patches, and upgrading VMWare tools, I have a group of servers that hang. It seems it can take anywhere from a week to several weeks for it to occur. I have monitored the servers with PerfMon and do not see anything abnormally increasing. It's almost as if it's just a sudden hang. You can no longer RDP to the servers. Connecting to the VMWare console of the VM reveals the VM in a hung state unable to get to the login prompt. Only power cycling the VM brings it back. Has anyone experienced this behavior? Any suggestions are much appreciated.
