Error 5566 When Open Infopath Form in Sharepoint

Old problem with infopath form services in sharepoint.

Before i forget to make a documentation for this problem solving, I decided to make an article in this blog.

The solution is edit web.config file.

Find this configuration

<system.net>
<defaultProxy>
<proxy autoDetect=”true” />
</defaultProxy>
</system.net>

Change to

<system.net>
<defaultProxy>
<proxy usesystemdefault=”false” proxyaddress=”http://xxx.xxx.xxx.xxxx:yyyy/” bypassonlocal=”true” />
</defaultProxy>
</system.net>

“xxx.xxx.xxx.xxx” is your proxy server (ISA)

“yyyy” is the port of the proxy.
