Windows Interview Questions
- Can you use Start->Search with DFS shares? Yes.
- What problems can you have with DFS installed? Two users opening the redundant copies of the file at the same time, with no file-locking involved in DFS, changing the contents and then saving. Only one file will be propagated through DFS.
- I run Microsoft Cluster Server and cannot install fault-tolerant DFS. Yeah, you can’t. Install a standalone one.
- Is Kerberos encryption symmetric or asymmetric? Symmetric.
- How does Windows 2003 Server try to prevent a middle-man attack on encrypted line? Time stamp is attached to the initial client request, encrypted with the shared key.
- What hashing algorithms are used in Windows 2003 Server? RSA Data Security’s Message Digest 5 (MD5), produces a 128-bit hash, and the Secure Hash Algorithm 1 (SHA-1), produces a 160-bit hash.
- What third-party certificate exchange protocols are used by Windows 2003 Server? Windows Server 2003 uses the industry standard PKCS-10 certificate request and PKCS-7 certificate response to exchange CA certificates with third-party certificate authorities.
- What’s the number of permitted unsuccessful logons on Administrator account? Unlimited. Remember, though, that it’s the Administrator account, not any account that’s part of the Administrators group.
- If hashing is one-way function and Windows Server uses hashing for storing passwords, how is it possible to attack the password lists, specifically the ones using NTLMv1? A cracker would launch a dictionary attack by hashing every imaginable term used for password and then compare the hashes.
