Multiple reserved ephemeral ports entries in the registry? RRS feed

  • Question

  • Hi everyone.

     

    This is my time at these forums and I hope i am posting in the right place.

    I have an issue with some software that fails to bind to a UDP on reload due to the security update MS08-037 being applied. The link http://support.microsoft.com/kb/812873/ explains a workaround which I am happy to do.

    The problem is that I already have the registry key entry there with a range of ports specified. What I would to know is if it is possible to add multiple ports to this registry entry? Do I need to use a comma "," between entries or is it not possible to do this.

     

    Any help is most appreciated.

    Thanks

    Hi Dean

    Once you've created a Multi-string Value, you will see that the reg entry type is now called a "REG_MULTI_SZ. This type of entry allows multiple values, line for line, not delimited by anything (no comma, semicolon, etc). Rename it as the article mentioned, then double click on it. A box will show up allowing you type in multiple values. Type in your first value in the first line, then hit the Enter button, and it will go to the next line. The Enter button in this case acts like a carriage return going to the next line. Each line is an entry.

    I hope that helps.

    As for the reserved ephemeral ports (also known as the 'service ports), I have a blog on it that explains it a little. I hope you find it helpful.
