You know the score. You've used VMWare ESXi to create a bunch of legitimately licensed win2k3 servers to emulate a client test environment. You let them run windows update regularly, life should be sweet.
But no. At some point, you might decide to allocate more memory. Then the windows activation page pops up. But it doesn't. You get a BLANK windows activation page.
Joy. So you hit the Microsoft support site and find this, and hack the registry to no avail. Then you google search (it seems to be a very common issue) and change screen resolution, etc. To no avail.
Then you finally uninstall IE8 from the machine. And activation finally works.
2 hours wasted this morning. Thank you, windows activation team, for creating a utility in windows that is browser dependant. You idiots.
