I Have configured my samba machine as a member  of Windows AD (win2k3 Machine). All the configuration went on successfully when i execute net ads testjoin i get output as "OK" and i can see my samba machine in AD computers and users. also i get a proper output from wbinfo -u -g. My kerberos tickets are valid. Now the problem im facing

Case1: When i enter the machine name of my samba server in Run Box Of Winxp it is popping up for a user name n pass like Samba/<username> (where Samba = my samba server name) when i enter a valid ADS domain user name it doesnt validate it but when i enter a valid linux user/pass it gets authenticated

Now in Case 2: when im entering the ip address of my samba server in "Run" Box it is asking for TIPTON1/<username (where TIPTON1=my ads name) when i enter a valid user and pass of windows it doesnt authenticate also when i enter a valid user and pass of linux it doesnt authenticate.

The Only Condition when im able to access the samba shares is when i log into winxp with my ADS Domain Profile and try to access the Samba share from My Network Places><ADS DOMAIN>Samba Domain.

I would like to use all the ADS accounts to authenticate the users and i dont want to use my linux usernames and passwords.
