Wow, brilliant. Thanks Jim. Could you perhaps enlighten me as to why this error occurs and what I should be looking for as the cause of the problem? The thing is, after getting about 22 errors in the spate of 1 minute, I haven't received them again, so I don't know what I am looking to fix. The thing is also, I got one alert for every Server Publishing rule that I have so the problem is not just with one Client Address Set, but maybe something more sinister. My newly established VPN possibly? Your comments?

Open the ISA MMC, edit the "Client Address Sets" data and re-save the rule. It should fix your problem. Jim Harrison [ISAQFE] Read the help, books and articles!

The failure occurred during Initialization of reverse Network Address Translation (NAT). because the configuration property of the key SOFTWARE\Microsoft\Fpc\Arrays\{6DC96C7B-F3E9-402A-859B-91AD423666A3}\Pub lishing\PNATServerMappin gs\{F22A161A-0B2F-49F1-99F0-9B39B398B9D4}\ClientSetsExcluded could not be accessed. Use the source location 2.546.3.0.1200.166 to report the failure. The error code in the Data area of the event properties indicates the cause of the failure. For more information about this event, see ISA Server Help. The error description is: The system cannot find the file specified. Would someone perhaps have any inkling of an idea as to what this means?
