RPC Server is unavailable

[matthewfarnell]

hi, we have started having an issue recently with group policy not applying things here and there.

We recently re implemented group policy printer deployments as our old method was getting a bit sluggish. So cut a long story short we built the gpo's, linked them to the container, right clicked and did an update on the ou and got a box which counted through the pc's. they all gave an error code 800706ba. the RPC server is unavailable.

 

We did a bit of googling and saw it is a firewall issue. So, we disabled the firewall on the pc's (and checked them).

Still same error. We've also tried removing our antivirus (Sophos) from some of the pc's to test it and no luck.

 

Any one had this before

Could be a number of things, but here are a few things to tick off the list...

 

Do your host names resolve using ping -a ipaddress or nslookup? (if not, likely a DNS issue)

 

Have you configured these GPO items to allow remote management...

Computer / Policies

Windows Settings / Security Settings / Windows Firewall with Advanced Security

Inbound Rules

- Windows Remote Management (HTTP-In)

 

Administrative Templates

Network / Network Connections / Windows Defender Firewall / Domain Profile

- Allow ICMP exceptions Enabled

- Allow outbound source quench Enabled

- Allow inbound echo request Enabled

- Allow inbound file and printer sharing exception (your local subnet)

- Allow inbound remote administration exception (your local subnet)

- Allow inbound Remote Desktop exceptions (your local subnet)

 

Windows Components / Windows Remote Management (WinRM) / WinRM Service

- Allow remote server management through WinRM (*)

 

Computer / Preferences

Control Panel Settings / Services

Service (Name: WinRM) STARTED

Service (Name: RemoteRegistry) STARTED

 

 

You'll have to run a GPUPDATE once you've made sure these apply to your test computer in a specific OU.

 

EDIT: And a reboot for good measure :-)
