One XP Home and two XP Pro

[Guest]

Computer A: 'Jerry' 192.168.0.1 - XP Home
Computer B: 'Roy' 192.168.0.3 - XP Pro
Computer C: 'Old' 192.168.0.188 - XP Pro

All updates on all computers from MS Update.
A to (B and C) No problem - full share of all drives and all files.
(B and C) to A Will not access ANYTHING.
I can ping from any to/from any and get proper response - all identified.

'Home' will not allow access by 'Pro' - print/file share enabled on all.
None of the computers has a password set.
ICS works fine (Home is internet server).
Print sharing works fine (one printer LPT on computer A) accessed by all.

I'm yanking out what remaining hair I have. Can someone PLEASE help?

Hi
Successful Sharing involves some general consideration in Network settings,

As well as specific adjustment of each computer according to what is allowed
to be shared.
