I recently faced a strange issue after configuring and trying to connect to an SSL VPN hosted on a DrayTek Router. I initially updated the DrayTek Smart VPN Client to the latest release 5.6.3 which did not resolve the issue. I then decided to change the SSL VPN Users password and identified that the below error was a result of using the £ symbol in the SSL VPN Users password. Once I removed the £ symbol from the password I was able to connect without error. It’s possible that other special characters may cause the same problem so if you also encounter this error I would initially suggest simplifying your password for testing purposes.
When you try and use the Out of Office feature in Microsoft Outlook you may recieve the following error message:
Your automatic reply settings cannot be displayed because the server is currently unavailable. Try again later.
When you look at the Application Event Log on you Exchange Server you will see Event ID 1310 logged from Source ASP.NET 2.0.50727.0
Exception type: ConfigurationErrorsException
Exception message: The value for the property ‘maxRequestLength’ is not valid. The error is: The value must be inside the range 0-2097151. (C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\exchweb\EWS\web.config line 2376)
We need to modify the “web.config” file which can be found here “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\exchweb\EWS\” you need to open the “web.config” file using Notepad and then use the “find” feature in notepad to quickly locate the following line in the file
<httpRuntime maxRequestLength=”52428800″ />
The default value is to high “52428800” so you need to change it as follows
<httpRuntime maxRequestLength=”2066661″ />
The final step in resolving the issue is to save the changes you have made to the “web.config” file and restarting the “Default Website” under IIS Manager (Administrative Tools)
