SYMPTOMS
Windows 2000 Globally Unique Identifiers (GUIDs) are available for querying specific Domain Name System (DNS) types. With some GUIDs, including the FTP GUID, host name resolution may not succeed.

When the GUID translation does not succeed, the WSALookupServiceX call does not succeed and generates a "WSATYPE_NOT_FOUND" error message. Note that this problem does not occur if other programs that do not use GUIDs (for example, Ping) happen to touch the host in question before this call is made.



CAUSE
This problem occurs because the GUID is not translated into the correct DNS type. In the case of the FTP GUID, it is translated to DNS_TYPE_ZERO.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 1.
