Okay, Like every user on this thread, I've been getting the change your\nsecurity settings, Enable Userdata persistence - 0x800A0046 error on all but\none of my Windows 2000 Servers, these are not Domain Controllers.\n\nI've read all the threads and have tried all the suggested Microsoft fixes.\nI realized these fixes have worked for some people but they have not worked\nfor me. To recap:\n\nMethod 1: I am using the Administrator account as a Member Of only the\nAdministrators group and nothing else.\n\nMethod 2: I downloaded SC.exe that doesn't come builtin with Win2k from\nftp://ftp.microsoft.com/reskit/win2000/ I got a "Success".\n\nMethod 3: Administrator and Service is already part of the Impersonate a\nclient after authentication policy. I even tried adding them again.\n\nMethod 4: The Automatic Updates Service is logging in fine as a Local System\naccount.\n\nMethod 5: I am not using any remote control software. I have direct console\naccess.\n\nAnd finally yes, I've logged off, even rebooted the machine everytime.\n\nI do however get the fuzzy Automatic Update globe with Windows logo icon on\nthe lower right hand side of the taskbar. W hen I place my mouse cursor over\nit, it says "Updates are ready for your computer, click here to install your\nupdates" but disappears when I click on it. It will reappear after a little\nwhile.\n\nRight now, my work around is to access v4 Windows Update by clicking on "Use\nAdministrator options" on the left hand side and then Windows Update Catalog.\n\nI really hope Microsoft doesn't ignore this and continue spitting out their\ntypical methods as the ultimate fixes for this issue since there are people\nwho've done them and still have non-working machiness because it is pretty\nfrustrating to think our servers are not being updated properly in light of\nthe Internet worms that have been in the news lately.
