The VM contains a Win2k Exchange Server (32Bit) wich runs most of the time very well. But from time to time the complete VM freezes. Everytime we need a few reboots to make them run again. All this appears if the Virtualbox Guest Additions are installed. If we remove the Guest Additions the machine normally powers up again without the many reboots and freezes. Is there a chance to get the VM normaly running with the Guest Additions installed? Thanks in advance. Yours faithfully Fischer" defect closed guest additions VirtualBox 3.2.8 obsolete Guest Additions Windows Windows
