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!

ISA 2004 RPC issues

Asked by smcmcnutt in MS Forefront-ISA, Network Software Firewalls

Tags: , ,

My question would be:
How do I resolve the RPC/connectivity issues within my ISA 2004 server?
Details/Description:

After Installing ISA 2004, regardless of applying Service Packs, I receive Netlogon Errors (EVENT ID 1053): Windows cannot determine the user or computer name. (The RPC server is unavailable. ). Group Policy processing aborted.
If I try to add a domain user, to the Administrators group of the server, I receive a message:
RPC server unavailable.
The server logs the following error:
This computer was not able to set up a secure session with a domain controller in domain MYDOMAIN due to the following:
The RPC server is unavailable.  
This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator
It's acting like ISA is blocking RPC traffic.
There is a trendomous pause when logging on to the machine with a Domain account.  ISA does function, though.  If I set up VPN, create a local user, then I can log in.  If I try to VPN using a domain account, I can not log in.
When I run netdiag, without ISA 2004, all looks ok (everything passes)
When I run netdiag, with ISA, I get error, referencing DSbind

Server/Device Info:
ISA 2004 (SP3)- ALthough Issue seems to occur on each SP
Windows Server 2003 R2
