The system cannot log you on due to the following error: The RPC Server is unavailable

Hello,

I´ve got the following problem:

One of our Terminal Server 2003 from two days ago to this day on each morning i´ve received the following error from all users:

The system cannot log you on due to the following error:
The RPC Server is unavailable

When i´ve tried to access remotely (RDP) with the domain administrator account i also get this message.

I was looking at the knowledge base and verified what are the common solutions:

1) The firewall is disabled
2) The DNS are from primary and secondary DCs (and i can connect them by IP or Name)
3) The IP Address and Subnet mask is configured correctly.
4) The DNS entry of the Terminal Servers are correct.
5) I´ve verified the RPC services and its running

If i restart the terminal server the problem is solved until the next morning...

So i dont have many clues here and thats why i´m asking to the Experts :)

Thanks,
Paulo

Yes, agree with goyal_251, if you have DHCP enabled then try "Default" option or if you have static IP then try "Enable NetBIOS over TCP/IP".

1. Also verity correct DNS settings.
Troubleshooting "RPC Server is Unavailable" in Windows -   http://support.microsoft.com/kb/224370
 
2. Verity correct Time and Time Zone settings.
 
3. Verity that "TCP/IP NetBIOS Helper" is running and set to auto start after restart.
 
 4. Verity that "Remote Registry" is running and set to auto start after restart.
 
Its recommended to reboot the computer after changing the required settings.

goyal_251,

Well since this Server has a static IP Address the Netbios over TCP/IP shall be disabled automatically , but eventhough i´ve disabled it. Tomorrow i´ll verify if this works.

abhijitwaikar:,

All the solutions pointed are correctly configured or working.

thanks,

Since this solutions was the only different from the setting in my scenario, i´ll assume that Disabling the Netbios over TCP/IP was the solution. At least for the last 3 days everything is fine.

Beeing so i´ll accept this solution as the correct one.
