Am an engineer working in Al Rostamani Communications LLC, Dubai, UAE & we are the Gold Partners of McAfee in the region.
We have several reputed government & private concerns in UAE where we've installed McAfee ePO starting from version 3.5 to 4.5 with the latest patch
We've many important clients for whom we've setup ePO 4.0 with the latest patch on Windows 2003 with no issues. The last project I was involved in involved an upgrade on ePO 3.6.1 to a cluster redundant solution. I've successfully brought up a new ePO 4.0 server with the same policies & settings of the existing production server and on release of ePO 4.5 Patch 1, we've setup the Windows 2008 Enterprise R2 (64 bit) cluster for SQL 2005 SP3 and ePO 4.5 with no issues.
Please feel free to contact us before blaming the partners of McAfee in total...
