System Error: 11004 Winsock: Valid name but no record (NO_ADDRESS)

April 13th, 2010 admin

Every time I hit a Flexlm issue it seems to be a different fix!

Thought I’d share this particular one with you as it took me a while to figure out :-)

Had a client approach me with a laptop running Wildfire Pro/E 4 and Pro/E 5.   If you’re not familiar with Pro/E, it is a CAD package which just happens to use FlexLM as it’s license server.    FlexLM is very common as a license server so you’ll probably find this problem with other products.

Now I don’t know why, but version 4 worked, but version 5 didn’t?   Both using the same license settings.

Looking at the license status (in this case using a tool called ptcstatus.exe) gave the following error:

Warning (-96): License server machine is down or not responding.

FlexLM Licensing error:-96,7

System Error: 11004 “Winsock: Valid name, but no record (NO_ADDRESS)”

Now in this case, the license server was of the form “licence-server.companydomain.com”.    The odd thing was that at the start of the license status command was the following:

“License Server is UP: <license-server>”

So it must be talking to the server right?    I confirmed this with a ping to license-server.companydomain.com.

The key to fixining it was when I noticed another comment “Hostname: license-server”.

Not it’s not a fully qualified domain name – and if you try and ping the hostname it’s unresolved.

So the solution – add a line to the hosts file commonly found here:

c:\windows\system32\drivers\etc\hosts

Simply add a line with the ip address and hostname and you’ll be up and running!

    I cannot fix this problem. I tried to enter in the hostname, but I couldn’t save the file because it said I did not have the proper permissions. I changed my permissions and when I saved the file, it still did not work. Because I changed my permissions a bunch of my icons on my desktop changed to a weird default picture as well. Please help.

    Hy Tyler,

    Easiest way around this is to right click on the icon for command prompt, and select “run as administrator”.

    You can then

    cd \windows\system32\drivers\etc

    and then run:

    notepad hosts

    This should then allow you to save the file ok.

    Good luck!
