Stable on a standard Win2k server install or not? I suspect you mis-read, or the article was badly written/edited. That combination _is_ specifically mentioned by Microsoft as a configuration known to exhibit problems post-MS04-011: http://support.microsoft.com/default.aspx?scid=kb;EN-US;841382 However, my reading of that KB article is not that that is the only configuration that may cause trouble. In particular: Note This problem may occur if other drivers or services do not load successfully. This workaround is specific to the Nortel Networks VPN client drivers. Also, as the hotfix that is now available to address this issue replaces these core files: Mountmgr.sys Ntkrnlmp.exe Ntkrnlpa.exe Ntkrpamp.exe Ntoskrnl.exe it seems quite unlikely that this problem would be specific to just one common VPN client configuration...
