I remember having the same problem, and it went away when I disabled simple file sharing to just have the old file sharing. I also couldn't access the c$ shares before I did this. If you really want to remotely shutdown the computer I guess you should disable it. I'll test it in just a second, I just got a fresh install of XP pro. Is this XP pro or home, cause home only has simple file sharing. Anyways, I'll test it, and if what I said is the case, I'll edit this to say what I did.

Ok here's what I did, I was using the main account on my computer, the one that is created when you install(it's an admin account).
1. Tried with simple file sharing on and no password with my username and failed with psshutdown
2. Set a password then tried a again with the password, still failed.
3. Turned off simple file sharing, took off password and tried with no password, still failed.
4. Left simple file sharing off and set a password, worked fine specifying an admin username and password with psshutdown.
Here's how you turn off simple file sharing, just open up my computer, and go to view>folder options...
under folder options click the view tab, and at the very bottom there is a checkbox to allow simple file sharing, but this is only in XP pro, uncheck that box, and click apply. You should now be able to shutdown that computer. I could be wrong, but that's how it worked for me. Good luck.
