The title says it all. I have had this minor annoyance for some time and finally got around to asking here.
I have two internal HDD's and a USB Connected External HDD on my desktop set as mapped drives on my laptop.
When I signin to these drives on my laptop I always check the remember credentials box, but when I re-boot the laptop I always have to signin to those drives again.
The desktop is XP SP3, the laptop is W7 Build 7000.
