As per ur senario, ur environment looking like Workgroup not a domain environment .
By default 2000 server and XP mechines will be in workgroup model.
Have u installed Active Directory in Windows 2000 server? … not then it wiil be workgroup model.
If it is a workgroup model,
1.Ensure that all the 3 mechines ( 2000 server, PC ‘A’ and PC ‘B’ ) are communicating with each other by using PING command.
2.Ensure that all the 3 mechines are in same workgroup.
3.Ensure that u have created both “abc” and “xyz” users in all the 3 mechines.
But this setup won’t give much security. If u need more security, I will prefer u to go with Domain Environment. Which will give u the centralised user database and security. So that u can create user accounts in the server itself. no need to create in client mechines.
Pls go through the <a href=”http://www.thatdamnpc.com/57/”> link </a> will give u the basic idea about workgroup and domain environment.
If you have any concerns let us know..
Thanks & Regards,
