Got the same error.
The solution was a registry fix mentioned in another forum thread from 2011.
My setup was 2 Windows 2012R2 servers in a domain.
If i tried to add the proxy using these accounts it worked:
- domain account, like domain\useraccount
- with the proxy local administrator, like proxyserver\administrator or IP\administrator (10.10.0.44\administrator)
If i tried the exact same thing with a local administrative user from the proxy server it did not work:
- proxyserver\veeamuser or IP\veeamuser or .\veeamuser
Tried creating another local admin account but got the same error.
Tried the veeam checklist: FW, UAC, File and printer sharing, VSS remote registry etc and access to admin$ worked fine.
The only that made it work was a old Veeam-forum write from 2011 which described a registry fix that is describe my MS as "This value enables the remote administration of the print drivers on a server within a workgroup.":veeam-backup-replication-f2/v6-cannot-install-proxies-t9612.htmlhttps://support.microsoft.com/en-us/hel ... -on-a-wind
