network access to shares always try to authenticate but fails

[Rob M]

I have 3 PCs running XP Pro on a pear-to-pear network. On one of them I
cannot access the shares. I can see them but if I click (using Win Explorer)
I get asked for a password. If I use Simple File Sharing it ask for a
pasword for the guest account - although there definately is none (I have
verifie this with "net user guest"). If I use Classis File Sharing and
assign rights to a known user, the password fails. It just keeps taking me
back to the login dialogue box.

Does anybody know how to delete and re-install XP Pro authentication
services? Or have any other ideas?

Thanks,
Rob

Do all computers have the same username and the same password?

I've done a bunch more work on this. It isn't an issue with usernames and
passwords (however the main admin user and pword is the same on all three).
The offending machine is an x64. When I use Windows Explorer on the X64 I can
access the shared folders, However, if I scroll down and drill down into My
Network Places -> Entire Network -> Windows Terminal Network -> Workgroup ->
x64 Machine -> Share "it stills prompts me for a password". This is bizarre.
It always prompts me for a login from the machine itself. If I have Simple
File Sharing enabled, and try to access a share from a network PC, it prompts
for a password for the guest account. Again, this is not supposed to happen.
If Classic File Sharing is enabled, then the network machine is prompted for
a full username and password but nothing works. I've expanded the rights to
give anybody and everybody full control but to now avail. I've played with
security policy settings that looked like they might make a difference but no
change. I spent 2 hours with MS tech support letting them go through the
motions today - no resolution. I have another 2 hours scheduled with them
tomorrow. I've spent about 20 hours over the weekend researching MS support,
technet, forms, user groups, googling etc. There is no mention of this kind
of behaviour for any OS within the last 4 - 5 years.

Any ideas are appreciated.
