I can't start a webserver , "Webserver cannot start, error 60"

[HemoDyn]

I am just getting familiar with the Web features of LabView. I went to Tools->options->Web Server:Configuration, and checked 'Enable Web Server', and click ok (using the defaults).

When this is done a dialog pops up with the following error "Webserver cannot start, error 60". I don't think I have an processes running that are hogging the port, so I'm at a loss for why it wouldn't start.

Hemo,
which version of LabVIEW are you using? Do you have a beta version?
This error indicates that your machine is already running a web server on port 80 (such as a copy of LV 6.0 with the web server running).
If you cannot find which application is using this port, then just change the default port, in the LabVIEW version you are trying to use, to something else than 80.

Yeah, changing the port to something other than 80 worked. I must have a process running that I don't know about. Thanks for your help

Hi Zvezdana,

I am getting same Error 60 using TCP/IP method of communication. In Tools>Options I checked TCP and put port 12344.
The reason I did this is because RT Communication Wizard assigns this port number to my three VIs (NPL,TCL and Host).
During the download of NPL to cFP-2020 device which is connected to my PC over crossover cable there are two pauses.
Both pauses happened to occur when TCL and NPL are being downloaded to cFP at that moment.

I am new in Real Time.
The code I have works fine if I use LabVIEW for Windows.
But once I want to move to RT and once I use Rt Communication Wizard to build those three VIs these TCP errors start to occur.
Is it that the code is taking all memory?
...

I need some directions.
I can attach my code
next time I post a comment if you want me to.

Thanks a lot,
