Unable to login to samba on Linux

I tried to search for a solution for this problem but couldnt.
So anyone out there plzzzz help

I am really desperate

I have samba configured on the linux box.

1.Steps that I followed to configure samba.
[share]
path = /<my path>
writeable = yes
guest ok = yes

2. I added a user in the smbpasswd file using the command
smbpasswd -a <any user that is going to logon from windows>

3. I kept the security level to user. I cannot make it share because I need to delete some files and share level doesnot allow me that

4. I login to the windows machine and in the run I type
\\<host>\share

When I try the fourth step on the windows box I get an authentication pop up
When I try to login with the user I specified in the smbpasswd file.It does not login and comes up with the username <computer name of windows >\<username>.

I even tried mapping the users but couldn't do it I still get the authentication pop up

please help...
note : I cannot change the mod to 777 for the folder.

Any suggestion please.

can you try without a username/password (configure samba to not require). For a really really basic samba to start with you can try this:

[global]
workgroup = SIMPLE
[test]
comment = For testing only, please
path = /export/samba/test
read only = no
guest ok = yes

you can then add to this and see what is causing the hangup
