Win can access Xp laptop but Xp can't access win7?

Why is it that I can do anything to my Xp laptop shares from Win7 but Xp asks for a username and password to access Win?

It's all feeling very Vista'esq again

Am I supposed to know what this username and password is? Did I create a username and password while not paying attention?

I've turned off password protected sharing in advanced sharing settings, turned on file and print sharing, both computers are joined to WORKGROUP. I went through the file sharing setup wizard on Win7 which spat out a password at the end but like so what? There's no username to go with it and it doesn't work if you enter that password from Xp anyway.

Can someone please put me on the right track here?

I hope that MS realise that there's an ocean of idiots like me that just want to copy a file from PC A to PC B at home and that the wizard should set all this up for us and not make us google around for half an hour just to find out how to copy a file from box to box. Unless it's intentionally not backward compatible?

Thanks

Did u check the Local Security Policy? Please go Local Security Policy->Local Policies-> User Rights Assignment and then check ( Deny Logon on locally) and remove Guest from the list. may be this is helpfull for you if not please let me know

Nope, Xp still asks for a username and password.

..and now if I add 'Guest' back to that list, it automatically changes it to 'PC-Name\Guest'.

Go same location and remove GUEST from Deny Access to this computer from network. Please do all settings in XP and as well in 7

Sorry, still doesn't work.

Maybe you could test it on your network before posting?

Thanks

Homegroup connections:

Allow windows to manage homegroup connections or use username and passwords to connect to other computers?
