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.

Unable to resolve hostname after establishing vpn connection

Asked by tastas in Virtual Private Networking (VPN)

Tags: , ,

I have Netscreen Remote VPN client installed.  I am able to establish a VPN connection.  However, I am not able to resolve the hostname or hostname.company.com.  I am able to ping the internal IP address without any problems.  In order temporarily resolve the issue, I had to add the hostname to the host file.  Another tempt solution is to change the DNS settings to static.

Based on the Netscreen remote log, it had received the DNS successfully.  However it is still not resolving the internal hostnames.  See log below:

I know the DNS server is working probably because I could resolve all hostname by doing a nslookup and changing the server to internal server.

Here are some steps I have tried; but no luck
1.  Changing the Provider Order and Adapters and Bindings Order in Network Connections --> Advanced --> Advanced Settings

2.  Tried changin the kerboros at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\ Kerberos\Parameters MaxPacketSize to 1
