SUSE Linux Enterprise Server 11 Service Pack 4 (SLES 11 SP4)
Change Guardian 4.0


Protocol negotiation failed error when deploying the Windows agent from the Change Guardian Agent Manager. 
SMB1 disabled causing installation issues with the Change Guardian Agent Manager from the CG Appliance.
CG Agent Manager deployment of the windows agent fails with protocol negotiation error for SMB2.


To work around the issue do one of the following. 
1.)  Install the Windows Agent manually.
2.)  Enable SMB1 on the target machine to allow remote installation.  

Once Change Guardian supports SLES 12 SP4 or RHEL 7.3 which both support SMB2 the workaround will no longer be needed.  


Change Guardian 5.0 Appliance uses SLES 11 SP4 which uses SMB1 and does not support SMB2.  Also RHEL 6.7 does not support SMB2 and requires SMB1 to successfully support CG Agent Deployment.
