I have almost the same problem: Win2k3server EE with 42 hotfixes to integrate. WindowsServer2003-KB890046-x86-ita.exe and WindowsServer2003-KB918899-v3-x86-ITA.exe among them. No errors while integration, smooth install, but Automatic Update pops up with these two files to download. I tryed several times, even downloading them again before new integration, but unsuccesfully. Every time these two update are not recognized as integrated.
