Hi Joey,
I made the 2 changes you specified, changing the unenabled to Automatic and rebooted the XP system. I Also checked the workgroup name while I was at it. It was WORKGROUP as expected.
With bated breath I cleared the shared login info (after cold starting the WDTV). Videos - Windows Shares - MAINPC and it displayed the anonymous login screen. Again NOTHING entered was accepted 
I brought my friend’s WD TV SMP home and swapped it with mine. Selected MY network and password then selected MY PC. IT BROUGHT UP THE ANONYMOUS LOGIN SCREEN!!! (Unexpected)!
I entered my account name and password and off it went… PERFECT…
Selected my NAS and it showed the anonymous login screen (as expected). Ok, Ok and off that went… PERFECT.
I didn’t expect the login screen on the Windows Shares but it worked so okay!
Thanks for your help but sadly, your solution didn’t work
Any more solutions?
Please?
The problem has got to be XP but what?
