SYMPTOMS
Windows 2000-based clients that are using a NetBIOS scope may be unable to communicate with other Windows 2000-based clients, even though they are in the same scope. Microsoft Windows NT 4.0-based clients can communicate with the Windows 2000-based host, even though they cannot see each other.



CAUSE
The clients are unable to connect to each other with a Server Message Block (SMB) session. A TCP session is established successfully and the calling computer sends a negotiate packet to the target computer, but the target computer never responds. The calling computer then cleans up the session after the time-out period has been reached.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Windows 2000 service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
NOTE: The use of NetBIOS scopes as described in this article is included only as a convenience for limited situations in which they absolutely must be used, and no other alternatives exist (such as VLANs, IPSec, more restrictive use of NTFS and share security, and so on). The use of NetBIOS scopes is discouraged, and there are no guarantees that NetBIOS scopes will be supported in future releases of Microsoft products.
