After installing Acronis True Image 2009 Build 9770 on my Asus V1V laptop (Vista Business 32 bit) I had no access to computers on the local network, and no access to the internet. Vista's network diagnostics were unable to help. The machine IP address had also changed. Uninstalling ATI2009 and rebooting fixed the problem, and reinstalling restored the problem. Deleting "tdrpman228" from the upper and lower filter lists, and from the list of services (both in the registry) and rebooting appears to have fixed the problem. This fix is similar to the USB drive problem (http://www.wilderssecurity.com/showthread.php?t=222370) but that problem was supposed to be fixed in my ATI2009 build. ATI2009 developers: PLEASE TAKE NOTE! This is a tantalising product - the best when it works and the worst when it doesn't.
