Any error messages? What version I.E.?<br><br>You stated "reinstalled" NT....was that over the top of an existing installation?<br><br>Was IE reinstalled before the SP6 install? Due to the fact that these 3 installs (NT, IE, SP6) contain common files with different versions it may be very difficult to recover from version mismatch problems...depending on the order of installation/reinstallation.<br><br>Again, depending on the procedure you chose..you may want to uninstall SP6, uninstall IE (if possible)..reinstall IE and then SP6.<br><br>This is just conjecture on my part as I do not have the complete picture of your install.<br><br><br>let us know.<br>
