Windows NT 4.0 Service Pack 6a
Service Pack 6a (SP6a) resolves the SP6 issue with Lotus Notes and other Winsock based applications and provides the latest updates to Microsoft® Windows NT® Workstation 4.0 and Windows NT Server 4.0 (including Enterprise Edition). SP6a contains known Year 2000 updates for Windows NT 4.0. These Year 2000 updates are also available as separate Web downloads that customers may apply to a Service Pack 4 system. Providing these options gives organizations the flexibility to choose which path is easier for them to address Year 2000 issues. SP6a is not a required upgrade for Year 2000; Microsoft recommends that each customer consult the SP6a documentation and then determine whether to deploy it.

SP6a includes the following updates to SP6:
  • The update for the SP6 issue with Lotus Notes and other Winsock based applications. This issue prevents connecting to the server when the current user is not logged in with administrator rights. For more information on this issue see Article Q245678 in the Microsoft KnowledgeBase (KB).
  • In accordance with Microsoft's commitment to Year 2000 compliance, SP6a includes an update to the IIS 3.0 log converter utility, convlog. For more information on this see KB Article Q245329.
  • Winver.exe has been revised to allow the user to quickly verify whether a system is running SP6a.
If you installed SP6 or SP6a between November 22 and November 29th, please confirm which service pack you have by following these steps. If you already have SP6a installed, you do not need to take any action.

If you have SP6 installed, you can update your computer by installing the corresponding X86 or Alpha SP6a hotfix.


Warning: To avoid problems, including possible data loss, if you use both Microsoft Outlook and Computer Associates Inoculan, you should verify that you are using the latest version of the Inoculan drivers before installing SP6a. Please visit http://www.support.cai.com/ to obtain the latest drivers. Other applications and prior versions of Service Packs may be affected as well; see the Microsoft Knowledge Base article Q244652 for additional details.

SP6a is available in Standard Encryption or High Encryption (128-bit) versions for both the Intel x86 and DEC Alpha platforms. Both versions contain the same updates and differ only in the level of encryption. The Standard Encryption versions below allow you to choose a language for SP6a and select a specific downloading site.

Note: If you have previously installed 128-bit components on your system, download the High Encryption version.
