Win7 sharing "breaks" when I move a file to the shared location

Hi -

I'm stumped. Why does Win7's networking/sharing have to be infinitely more complicated than XP was?

I have a computer running Win7 Home x64 that I call "fileserver". My main day-to-day machine is a laptop running Win7 Pro x64. There are several other computers throughout the house all running WinXP Pro (32 bit).

I do a lot of video processing on my laptop, and whenever a file is done processing and ready to live on the fileserver, I move it over there. As soon as I do this, sharing for the computer called "fileserver" DIES. All shares on the machine become inaccessible, and all other machines lose access.

I can't fathom why this would happen, but it does. My workaround for the time being is to simply reboot the fileserver, which magically restores sharing. However, this is a horrible workaround since files of all types are being accessed from that machine all day long.

Any suggestions?

Thanks!

Update: I got to digging around a bit more with sharing permissions, security, etc and found that the ownership of the shared directories was sort of all over the place. In several instances, the "owner" of the directory in question was some unknown user with a long ID number.

I'm starting to think that every time I moved a file into a shared directory on that fileserver machine, my user ID on my machine sort of hijacked ownership of the directory. So I've tweaked a ton of settings and unified the ownership and security policy across all shared dirs, and we'll see how that goes.

I'm still interested in anyone's input though.

Thanks

Oh, and one other thing: I disabled "take ownership" for the "Everyone" user on all shares. Right now, each share has permissions set for three users: "Everyone" "File Server" (the main user of that machine), and "Administrators". Only "File Server" has full control. I hope this works!

Well, that didn't work at all. I moved another file to the fileserver, and BOOM, all permissions are BROKE until that machine reboots. What a colossal pain in the ass. Can someone please help??

Good grief, I forget about this for a week and still no replies. Thanks. :/
