I found this on google I was just wondering what is going on and why the /integrate command does not work as expected. To get around the problem until a solution is discovered, I extracted the update files using the /x command manually integrated KB885250 into the installation files. I am not sure, but wonder if it is somehow related to the mrxsmb.sys file that is being updated by KB885250. Note that KB885835 / MS04-044 updates the mrxsmb.sys file as well, but KB885250 contains version 5.1.2600.2598 - which is the newest version. Thank you. I hope a fix can be found. can we repack the kb to sfx instead?
