When trying to add one server as a Backup Proxy in Veeam (fully patched version 7) I am getting the error:
[ServerName] Failed to install deployment service.
The specified server cannot perform the requested operation.
--tr.Failed to create persistent connection to ADMIN$ shared folder on host [ip address].
--tr:Failed to install service [VeeamDeploymentService] was not installed on the host [ip address].
In looking this up, I tried a few things that did not fix it.
I disabled UAC completely on the server
I did the registry change
Made sure proper ports were open
I can browse from my computer at the local site to \\server\admin$ just fine and have full read/write capabilities with the account I am using to authenticate during the install.
All of my other servers worked fine, the only difference being they are all Server 2008 R2, and this is Server 2012 Datacenter.
I'm going to look back through the remote firewalls logs to see if I can see anything, but wanted to get this out there in case someone experience the same and could shed some light on the situation.
