The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

WMI : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

Asked by plq in Microsoft Visual Basic.Net, .NET, .NET Framework 2.x

Tags: rpc, getuserdefaultlcid, server

I have a vb.net 2005 program using .net framework 2.0 management classes, which loops through every computer on the local LAN and pulls back some WMI information.

When I run it from one particular Windows 2003 server, it fails on every computer with this message:

The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

I can run the program from any other computer and it runs fine. Even another win 2003 server with the same standalone domainless configuration.

1. All computers have windows firewall turned off
2. All computers have RPC and DCOM enabled
3. All computers have the same administrator password and thats what the 2003 server is using.
4. I CAN connect to WMI on any computer from the server, using Computer Management, WMI Control, and I can connect to every c$ using windows explorer
5. None of the computers are on simple file sharing or have forceguest switched on
6. All of the computers will work when the program is run from another server, but when the 2003 server runs the program, it only works for itself. The program does not specify credentials.
7. All the computers are fully patched

WMI logs contain the following

wbemcore.log:
