Do not re-register agent after re-install a server

29-Mar-2017 05:14 PM

From time to time we reinstall our terminalservers (50). After a re-installation the server register in the monitoring portal again. This is a problem because there are two servers in the monitoring with the same name! Is there a workarround (registry key or something else) available to do NOT reregister the agent and map the server to the "old" entry?

How does other customers handle this?

Patrik

Hi Patrik,

Can you please share the following details for us to analyze the case:


1. Specify the Operating System that's installed in this server?
2. Are these Servers cloud based? If yes, please share the service provider's name?
3. How do you reinstall your terminal server?

Regards,

Hisham Thorakkal

1 2012 R2 Remote Desktop Server
2 Not cloud based - on premise
3 We reinstall the server with a tasksequence (SCCM System Center Configuration Manager)
After windows installation we install the Site24x7 agent with a script
