Problems with XP home and professional - wireless network

I've a simple wireless network set up between three computers - two laptops and one desktop.  Both laptops run XP professional, and the desktop runs XP home.

Now, I can quite happily access both laptops from the desktop, and access the laptops from both laptops, but I can't seem to access the desktop from either laptop (that sounds confusing..!).  I can see the desktop is there on both, but the shared folders simply don't appear, and when I double click the desktop from the list of workgroup machines, I simply am told I don't have permission to access the computer.

I understand this may be an issue with XP pro vs home, but at the moment there's no way I can afford to shell out for the upgrade to professional.

Any advice would be more than welcome.

Since this is a P2P problem, read my TS page on this..  there is just too many things to cover in one comment on the thread.  After reading through this, you should get connectivity, if you follow the methods used here for troubleshooting...

BTW:  just because you have Home should not pose a problem, if you go about this correctly..  the issue lies with authentication, and if you enter the Home system while in safe mode, you will find that you will have access to things such as the Security Tab (NTFS only) on the Home system, just like in XP Pro..  (make sure you turn off Simple File Sharing as per my page..)

Thank you very much - it was the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA key that solved it in the end.

Much appreciated.
