Is this an agent job or a VBR job?

Have you checked the appropriate firewall rules are in place?

If firewall rules are set then this KB https://www.veeam.com/kb4185 may be of help.

Hi @toddor 

did you also check?

KB1230: Win32 error: The network path was not found. Code 53 (veeam.com)

Is the server in the domain or is it local?
Are you using the local Administrator?
If yes in manage standard credential use hostname\Administrator

regards

Hi @toddor -

Can you provide more info, as others above have suggested, on what specific task you’re trying to do? And, what product you are using? (VBR, Agent)

Some quick things to try:
* ping the device
* check DNS
* check firewall rules and windows UAC
* reboot VBR (if you’re using this) or the server in question

Let us know.

Please go to Backup Infrastructure to ensure there is no unavailable error.

HI @MarkBoothman 

    It’s an agent job. 

    When I test the port 445, it return success:

PS C:\Users\toddor> Test-NetConnection -ComputerName AS-FS1 -Port 445

ComputerName           : AS-FS1
RemoteAddress          : 192.168.1.11
RemotePort             : 445
InterfaceAlias         : vEthernet (Realtek PCIe GBE Family Controller - Virtual Switch)
SourceAddress          : 192.168.1.44
PingSucceeded          : True
PingReplyDetails (RTT) : 0 ms
TcpTestSucceeded       : True

@toddor  I assume you can access the C$ share share directly from the Veeam server?

Also Check the KB Linkstate posted above. Have you worked through the steps to ensure things like remoteregistrty is running etc?
