Default ports used for communication with the veeam installer service. Last week i rebooted one of the management servers i use, everything looked fine, but the veeam backup didn't run that evening. If you haven't done so already, back up the registry. For example, you add a vm with 4 disks to a job and assign a backup proxy that can process maximum 2 tasks concurrently for the job. If you still can’t get in I’d look at more fundamental issues, like time synchronization and DNS.Veeam Task Failed Error Failed To Connect To 11731. At this point you probably can browse to Admin$, and you should take a moment to make sure your firewall is on and everything is secured again.
Reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f
If the firewall is disabled and you still cannot browse can the backup server ping the proxy? Is there another firewall between them that’s denying traffic?.Note that you can test this by just shutting the firewall off, but don’t do that unless you’re protected in some other way (hardware firewall, etc.). If that makes browsing to Admin$ work then make sure you have rules to permit traffic between the proxy and the other proxies, and the proxy and the main backup server. Didn’t work? Is the firewall enabled? For troubleshooting try adding an explicit “allow any” rule for all traffic to & from the backup server.

If that works you should see the Windows directory on the remote computer. This may mean you need to use “net use” to map it so you can specify a different username. Do this from the Backup & Replication main backup server itself by browsing to \\COMPUTERNAME\\Admin$ using the credentials you’re going to use for Veeam.

First, try specifying the username as the full “DOMAIN\Username” format when you add it to the Backup & Replication console.You might want to consider taking a snapshot before this work, so when you discover what fixes the problem you can revert the snapshot and just implement the fix cleanly.

There are also ways to manually install the Veeam Transport Service that might be more helpful. I’d get it running with as close to a stock Windows installation as possible and then work from there if you need to secure things further. If you’re using a hardened Windows installation all bets are off, since the goal of hardening is to intentionally disrupt remote access. This is what worked for me on Windows Server 2016 when I was getting error 0x00000057, “Failed to create persistent connection to ADMIN$” and some other unhelpful messages. If you’re like me and seeing proxy install errors maybe some of these will fix you up. Every once in a while I struggle a little to add a new Veeam Backup & Replication hot-add proxy.
