hi,
I have following fail messages:

unexpected sockect error: 10093
Filename: unspecified
Line number: 0

after this, I click refresh button, then "Hostname lookup failed: host not found" presents.

ps: my OS is win7 and in a windows domain.

before this post, I lookup the forum, I get this:

Any help is great. thx.

Hi zalex,

Thanks for the question. Are you able to able to use any other terminal emulator to connect to the remote server?

Is it possible that a firewall is blocking the ability of SecureCRT to ask the operating system to resolve the hostname?

Are you using a short name or cname to try and connect?

If so, do you get better results if you use a fully qualified domain name or IP address?

[zalex]

Thanks.

Yes. such as Xshell, putty works well.

I check the firewall setting, there is no blocking policy for secureCRT.
However, "For your security, some settings are managed by your system administrator" appears at the top.

I use IP to connect.

so, the firewall maybe the problem.

Thanks for the information zalex. I am glad to hear that IP address works.

Out of curiosity, what firewall are you using?

We have seen this issue in the past, and it has been DNS or firewall related, but we have had reports of other causes.

If you get more information about what is causing the inability to use a hostname please post the information.

A programmer looked at this and would be interested in the following additional information:

• What TCP/IP stack/implementation are you using?
• Have all of the Windows 7 patches been applied?
