Error in v 4.0.0.116 - Add new device

[JamesinIT]

No matter which screen in Lanwsweeper I happen to be in, if I click "Add New Device" I get the following error:

String was not recognized as a valid DateTime.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.FormatException: String was not recognized as a valid DateTime.

I think I see what is happening, all of these machines appear to be offline due to people being at lunch or going home early for the weekend...

If you restart the service active scanning looks for computers seen in the last 14 days.
If the computers are offline at the moment you will get a RPC error (which can be ignored)
Next time the computer comes online it will scan normally and the last rpc error will be deleted.

This indeed appears to be the case of what I am seeing.

Which scanning method do you use?

I have a combination of Active Scanning and IP scanning. Prior to the update, if I click "Trigger scan" it would kick off and not present any problems.

This seems to have brough on another problem, I am getting nothing but RPC server unavialable errors since I applied the new install.

That fixed the problem for me, Thanks!
