RPC Server Is Unavailable when working with Group Policies

OK, I have seen several other answers on this, but I am not getting any different results after trying or looking into every one that seems to make sense to me (yes, I realize all things are relative). So, please forgive, what is sure to be an easy question to many of you, but when I go into GPMC and run the GP Results Wizard, I get the message "RPC Server is Unavailable." I have made sure that the RPC service is running on the DC and tried to select many different machines within the domain, with the same problem. Where should I look now?

Just in case this impacts anything in any way, the topology is this: Site 1=SBS 2003 Standard and PDC connected to sites 2 and three via VPN; Site 2 = Windows 2003 Standard as DC, primarily for DFS; and Site 3 = Windows 2003 Standard as DC, primarily for DFS.

Hope that someone can point me in a direction that works. I hate giving up, but I am wasting everyone's time around here while I try to figure it out.

Thanks,
Blaine

Generally I've seen this error occur when workstations were not added to the domain using the connectcomputer wizard, or have been moved from the default OU of MyBusiness\Computers\SBSComputers.

If either of these is the case you need to correct that.  If they have been moved from the default OU, they need to be moved back.  If the computer was not joined to the domain properly, then follow these steps to fix:

The following needs to be done with the client machine:
1.  Log in with THAT machine's LOCAL administrator account.
2.  Unjoin the domain into a WORKGROUP
3.  Change the name of the computer
4.  Delete or rename the following directory C:\Program Files\Microsoft Windows Small Business Server\Clients if it exists
5.  Make sure that the network settings are configured to get an IP address automatically (DHCP enabled)
6.  Reboot

Then on the server, from the Server Management Console:
1.  Remove the client computers if it still shows in the Client Computer screen on the Server Management Console
2.  Add the client with it's NEW name using the Add Computer wizard

Then, go back to the client machine and join the domain by opening Internet Explorer and navigating to http://servername/connectcomputer

If neither of those two items are true in your situation, then try running "gpresult" from the command line with /U and /S switches to see if you can retreive results that way.  

Otherwise, please check the event logs on both the server and workstations to see if there are any USERENV errors or any errors which could be related to this.

Great! I will give it a try this evening sometime, as long nothing else pops up. I will let you know the progress.

Sorry for taking so long, but I wanted to give due diligence to your suggestions. I have done everything you selected on several machines--to the letter. It does not matter what I do. I have also noticed that when I try to use the DFS MMC, I get the same error, "RPC is unavailable." So, I am increasing the points, because it seems to be affecting more than just the RSOP part of the GPMC. I was able to use the command gpresult to get the problem resolved with a couple of the machines, but as I try to trouble shoot other parts of my novice avility, the RSOP would be helpful. Of course, the DFS not working, makes me think something bigger is going on.

THANKS!!!!!

Just checking to see if anyone is still out there on this. I may have to break down and call MS.

Did you join your remote servers to your domain following the steps outlined here:  http://sbsurl.com/addserver?

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

I have tried it using wizards as described here and using the DCPROMO command. Did not get any different results. In fact, I did one of each to see. Does that help narrow it down any?

Thanks!!

Not really, since there are more steps listed in the paper than that... such as making sure that the time service is configured correctly.

Do you have GPMC SP1 installed?

Again, thanks for the help and effort. This seems to be more closely related to the firewall. I can manually disable the Norton Antivirus Worm Protection and the RPC and RSOP start to work appropriately.

thanks,

Seems as though that was the finding of someone with this same issue:  http://geekswithblogs.net/jemimus/archive/2005/01/19/20374.aspx
