Consider the following scenario. Server for Network Information Services (NIS) is installed in the domain. Server for NIS is included in Microsoft Windows Services for UNIX. You open the properties for users, groups, or computers in the Active Directory Users and Computers Microsoft Management Console (MMC) snap-in. In this scenario, the UNIX Attributes tab does not appear.

This problem occurs when one of the following conditions is true:

•	The computer that is running the Active Directory Users and Computers MMC snap-in does not have Server for NIS installed.
•	The computer that is running the Active Directory Users and Computers MMC snap-in has Server for NIS installed. However, a problem with the Nisprop.dll library prevents the UNIX Attributes tab from appearing.

To resolve this issue, use one of the following methods:

•

Install Server for NIS on the computer that is running the Active Directory Users and Computers MMC snap-in.

•

Reregister the Nisprop.dll library. To do this, follow these steps: 1. In Windows Task Manager, verify that no instances of Mmc.exe are running. Note If you are logged on to a Terminal Server, make sure that you enable the display of processes from all users. 2. Copy the Nisprop.dll file from the NIS subfolder in your Services for UNIX installation source to the %SFUDIR% folder on the computer on which you want the tab to appear. 3. Unregister Nisprop.dll. To do this, type regsvr32 /u %SFUDIR%\nisprop.dll at a command prompt, and then press ENTER. 4. Register Nisprop.dll. To do this, type regsvr32 %SFUDIR%\nisprop.dll at a command prompt, and then press ENTER.
