I’m having issues setting up a database during the install process.

Usually we recommend to create a service account in AD with the dbo rights for DeskAlerts database and run the server installation using this account (in this case, you should just check “use Windows authentication”). If you’re feeling better working with SQL accounts – it’s perfectly fine, just create a service account there with the same scope of rights (dbo for DeskAlerts db).

I am getting “Your server is configured to run in Active Directory mode. This client doesn’t support it or you have old version of the client.” message.

It’s possible that your machine isn’t in Active Directory domain. By default, DeskAlerts with Active Directory support doesn’t send messages to the outside of domain. You can change this behavior by logging into DeskAlerts Control Panel with administrator rights, going to the Settings -> Common Settings and check “Mixed authentication” under the “Active Directory” section.

I get the “Cannot Start Website” error.

Make sure that you have the administrative rights to the server, as this issue might be attributed to the lack of rights to change IIS settings.

Furthermore, please make sure that you don’t have any software that might be using the TCP port on the machine.

I accidentally went over the number of active license I can have at the time. What can I do?

You need to apply a specific unlock patch to force licenses re-calculation. Send us an e-mail to support@deskalerts.com regarding this issue and we will send it to you.

Apply it on a server and restart IIS. It should force the licensing library to re-calculate the active users.

You should perform an IIS Restart, this is a requirement for most of the server updates. And you also need to clear web browser cache
