As this is a server restore I would suggest you to check your Network Security settings. All your error messages too point out in the same direction.
- Hit Start button, then type in the search box secpol.msc and hit Enter.
- Then follow the path: Local Policies > Security Options > Network security: LAN Manager authentication level. Double click the option Network security: LAN Manager authentication level.
- Then choose from the drop-down menu Send LM & NTLM-use NTLMv2 session security if negotiated. Then choose Apply and OK to save the change.
You can also try resetting the TCP/IP address and see if this is helpful.
