The server must be running a functioning English-language
version of one of the following Microsoft Windows OSs:
-
Windows 2000 Server with Service Pack 1 or Service Pack 2
installed
-
Windows 2000 Advanced Server with Service Pack 1 or Service
Pack 2 installed (Microsoft Clustering Services must not
be installed)
-
Windows 2000 Datacenter Server with Service Pack 1 or
Service Pack 2 installed (Microsoft Clustering Services must not be installed)
-
Windows NT Server 4.0 with Service Pack 6a
installed
While, technically, Windows service packs can be applied
either before or after installing Cisco Secure ACS, if the service packs are
installed before the Cisco Secure ACS software, the process will go more
smoothly. If not, the Cisco Secure ACS installation program displays warnings
that the required service pack isn’t present. If a service pack message is
displayed, continue the installation, and then install the required service pack
before starting user authentication with Cisco Secure
ACS.
