is there not a redist update pack for win2k you can download?
http://support.microsoft.com/kb/922667 sp5 is available here
http://hotfixv4.microsoft.com/Window...U_i386_zip.exe got this address by requesting hotfix on the site and they sent this by email. Might not be full update though and may still need net which of course wont help.
If not are all your USB dongles the same?
