We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SYMPTOMS
When you attempt to log on to the Internet Information Server (IIS) FTP Service by using the DOS FTP client, the system returns a &quot;Home Directory inaccessible&quot; message. When you return to the FTP prompt, and use the Bye command to exit the FTP client, a Dr. Watson occurs in the Inetinfo.exe service.

NOTE: The credentials that are passed work correctly when you attempt to log on to other resources, such as domain logins or network shares.



CAUSE
For the IIS Services (WWW, FTP, NNTP, and SMTP) to function properly, it is imperative that the corresponding DLL files for the service are the same version.

For example, if a computer is running Windows NT Server with Service Pack 5 (SP5), then the version for W3svc.dll, Infocomm.dll, Ftpsvc2.dll must all have the same modified dates. If they do not have the same modified dates, the out of date DLLs in Inetinfo.exe will cause an Access Violation to occur. If the service that you are attempting to use is not running the proper version, the Inetinfo service will return a Dr. Watson (C0000005) error.



RESOLUTION
To resolve this problem, apply the latest service pack to the server (currently Windows NT 4.0 SP6a). If you already installed Windows NT 4.0 SP6a, you may have to reinstall it. Note that reinstalling Windows NT 4.0 SP6a requires you to reapply all post-SP6a hotfixes.

For additional information how to obtain Windows NT 4.0 SP6a, click the following article number to view the article in the Microsoft Knowledge Base:

246009 Windows NT 4.0 Service Pack 6a Available

NOTE: IIS 4.0, which is included in the Windows NT Option Pack (NTOP), was released before SP4. To successfully update problems in products that were included in the NTOP, Microsoft has bundled all fixes in subsequent service packs. Therefore, to ensure that all services are running the latest version, you must run the latest Windows NT service pack.
