Hello,
I had an interesting issue, maybe a bug.
On my office windows xp machine, in virtualbox I created new win2k virtual machine, mounted installation iso, and tried to install win2k server.
First, I was doing it from home in remote desktop session. The installation consistently failed - after I specified "Typical settings" for networking, soon after that the virtual machine was rebooting. Tried many times with different v.m. settings.
When I got to the office and tried the same in real session, i.e. not through remote desktop, it succeeded.
regards
