Surprisingly (or rather not), lot of people are having issues with that. Some even claiming that it is impossible to view Windows 7 Event Log remotely from an XP or Windows 2003 machine because "it's not designed for that". They are getting "Unable to connect. The network path was not found" error when trying to open Event Viewer, even though Services, Storage, Shared Folders etc are working
Problem is that Remote Registry service has to be running on Windows 7 machine and it's set to Manual startup type by default.
So, just start Computer Manager on XP/2003 machine, connect to remote computer (if you are not able to connect at all, check the firewall settings) and start this service manually first.
