This article provides answers why you are unable to install agents on Windows XP, Server 2003, and Server 2008 R2 Gold machines after installing Ivanti Patch for Windows Servers 9.3+.
The following platforms are no longer supported for use with agents as of 9.3:
- Windows XP
- Windows Server 2003
- Windows Server 2008 R2 Gold
The change is due to a movement in the industry to migrate from the use of SHA-1 certificates to SHA-2 certificates. Ivanti started participating in this movement and at the end of 2016 we began requiring the use of SHA-2 certificates for communication between Ivanti Patch for Windows® Servers agents and the Ivanti Patch for Windows® Servers console. The three operating systems listed above do not support SHA-2 certificates, and so are no longer valid agent platforms.
Windows XP, Windows Server 2003, and Windows Server 2008 R2 Gold are still supported for agentless scans.
