rpc unavailable errors
I have a server that I need to get into but everytime I try to remote desktop in:
I get an rpc unavailable error
I can bounce the machine but it still gives the same error after it comes back up. The rpc service is running on the machine.
Does anybody have any idea how I can get into this server without having to be at the console??
Thanks for any help

Is this server a Domain Controller or a Member server? If it is a member server, does it have the Firewall turned-on on the NIC?
Can you ping it's own IP address from the command prompt?

this is a cluster node and ha firewall off. I can ping by ip or hostname. I cant do anything that requires rpc on it though. However because there is an internal heartbeat connection on it , I ws able to reboot and look at services via WMI.

Here is the event log error
Logon rejected Unable to obtain Terminal Server User Configuration. Error: The RPC server is unavailable.
Have you checked everything with Active Directory to make sure it is healthy and also make sure that the TCP/IP NetBIOS Helper service is running on the server?
Also, this isn't by chance a K12 educational server is it? I've seen a piece of software common to K12 institutions shutdown ALL networking services once an attempt was made to log onto the server either at the console or via T/S.

Yes the TCP/IP NetBIOS Helper is running and AD is fine. I have 100+ other services which have no issues. This seems to be an issue with something local to this server.
No this is not a k12 educational server.

I was able to ssh into this server via the internal heartbeat connection. I ran netdiag and got the output below> Any ideas on how to fix this?????

Also, the dcs are up and have no issues. All 100+ of the other member servers are fine and there are no other kerberos issues.

I have reolved this issue. I reset the tcp/ip via netsh:
netsh int ip reset
I manually added the dc to the lmhost file: (this was to force it to use the pdc and make sure it knew how to get to it for kerberos)
10.1.1.1 "domain_name \0x1c #pre
10.1.1.1 "domain_name \0x1b #pre
I then rebooted the machine and let it pull a dhcp address.
Now, I could connect via rdp with the dhcp address. The last step was to go back and change all the ip configs for the nics back to the correct address and mask.
After this the netdiag output returned no errors and all was well.
thanks
