This may be a general connectivity problem not specific to ClickOnce. On client machines thathave this issuehave you triedusing browser toaccess a test file such as .htm on the same server vroot? Does that work?

Regards,
Sameer

Yes. The client machines are able to browse to .htm pages at this location. The users who are attempting to install this application must go to a registration page (same site) before get the chance to install. The users can also successfully browse to the publish.htm page.

Any ideas...???

Thanks

Hi,

I'm having the same problem.

I tried to connect to a webservice from a desktop application, and it throws this error:

system.net.webexception: Unable to connect to the remote server --> system.net.sockets.socketexception: no connection....."

Anybody knows how to solve this?

Thanks in advance..

Are you checking for security exceptions? Perhaps you are running afoul of a code access restriction on the client. I have run into that and found it to be a root cause when the thrown exception did not indicate that as the problem, since it was a sort of cascaded error or derivative error - e.g. a call back to the server runs intoa security restriction and causes a connection not to be made.

FWIW.

Sincerely,

This error is occurring during the installation so I am not able to do any exception handling. Are there any server settings (Windows Server 2003, IIS) that could be causing this?

Hi,

I have same problem does any one have solution to resolve this issue?
