How to apply a DLL hotfix on the LAC?

In this document we will go over the process of applying a DLL hot fix to the LAC.
The DLL will be sent to you by the support team.

After you’ve downloaded it and extracted the ZIP, perform the following steps:

1. Backup the Bastion folder so we have a fallback option in case of an issue.
   Default location is C:\Agat\Bastion
   

   

2. Stop the Bastion service:

   Stop-Service Bastion

3. Go the filters folder in C:\Agat\Bastion\filter

4. For each folder with the lync_access_control.dll, replace it with the one provided to you by Agat support
   

   

5. Start the Bastion service

   Start-Service Bastion

Verify that everything is working:

1. Open the latest log file of the LAC. Default location is C:\Agat\Logs\Lync_Access_Control

2. Take a look at the initialization entries and verify that there are no issues.
   If you are unable to find it because there’s a lot of traffic, search for ====== in the log:

   

3. Open the Bastion.xml file, default location is: C:\Agat\Bastion\Bastion.xml

4. Take a look at the take skype and grab one of the hosts there

   

5. From an external client (not the Bastion) enter the following URL in the browser:

   http[s]://<<host in channel>>/skypeshieldhealth

   
   The following should be the expected response
