I'm installed DLP 9.1 patch 1, in a 2008 server SP2 32 bits, whit .net 3.5 SP1 and ePO 4.6.
The deploy to workstations is ok (XP sp3, windows 7 SP1), but to the serves fail. The message in the Status Monitor is Product Conflict: dataloss2000 will not be installed.
The servers are 3 Windows 2003 sp2 and a 2008 server SP2.
sorry - server platforms are not supported for Host Data Loss Prevention - only normal endpoint platforms are.
But in the installation guide McAfee HDLP 9.1.100 for ePO 4.5 y 4.6 on the top of page 12 say
The following operating system software is supported:
W2003 SE SP1 or later 32 or 64
W2008 Server Enterprise 32 0r 64
AFAIK the KC is the most accurate information I'm afraid - I've not heard of someone installing host data loss prevention on a server platform, only the HDLP management components (and EPO etc).
Device control is scheduled to support server environments in HDLP version 9.2.
The section of documentation you are reading has a server section and agent section. The agent section refers to what environment you can deploy the DLP agent to.
