I am working on infopath designer and saved the template in a server. But now i need to use the same infopath form in different site in differnet server. How come i use the template in other server.
If you're dealing with a list form, then you cannot publish it to another server. A list form is tied to its list. You could export the list as a template and create another list based on that template on the other server.
With a browser form, you can save the xsn as a separate file. Then, instead of Quick Publish, go through the full Publishing steps, i.e. File > Publish > SharePoint Server and select the new server and library. You may also need to adjust data connections before you publish the form.
Do NOT use File > Info > Publish. That will do a quick publish to an existing location:
Instead, go the full publishing path from scratch: File > Publish > SharePoint Server etc.
