Resolving Web Service Errors After the March 2022 Ares 5.0 Server Update

Some sites are encountering an issue with the Ares Web Service after performing the Ares 5.0 server update released on March 1st, 2022. This issue causes the Web Service to respond with Internal Service Errors for all requests and can be fixed as follows:

1. Open the Ares Web Service Web.config file (default location: C:\Ares\Web\WebService\Web.config) in a text editing application such as Notepad++ 

2. Find the section of the file that includes the following text:

   <dependentAssembly>
           <assemblyIdentity name="log4net" publicKeyToken="669e0ddf0bb1aa2a" culture="neutral" />
           <bindingRedirect oldVersion="0.0.0.0-2.0.8.0" newVersion="2.0.8.0" />
   </dependentAssembly>

3. Change this text to read:

   <dependentAssembly>
           <assemblyIdentity name="log4net" publicKeyToken="669e0ddf0bb1aa2a" culture="neutral" />
           <bindingRedirect oldVersion="0.0.0.0-2.0.14.0" newVersion="2.0.14.0" />
   </dependentAssembly>

4. Save your changes to the Web.config file
5. Restart the IIS service
