Hi all.

I made an application in asp.net and, through the SDK, a workflow is executed.

I've tried it using my machine as a workflow server and it worked correctly.

However, when I put the application to connect to another workflow server on another machine, it shows me the following error:

[Win32Exception (0x80004005): The logon attempt failed]

Why can this happen?
Thank you
