After doing a deployment from the build server in the NZ timezone to the production server in the US PST timezone I started seeing the following exception:
---- Exception information: Exception type: ArgumentOutOfRangeException Exception message: Specified argument was out of the range of valid values. Parameter name: utcDate Request information: Request URL: https://www.mydomain.com:443/Site/ScriptResource.axd?blahdeblah ----
Turns out there were problems locating AJAX assemblies that, from the production servers perspective, were dated in the future.
The solution is to either wait for the timezone difference to sort itself out or to update the last modified date on the DLLS.
See the following link for an example of the latter.
