Fax Error "80070483" and File Extension Associations

thread796-1715541: Fax HTML File From VB.Net Using Fax Server on Network Server

Just thought I would pass this update along. I moved an old .Net program to a new 2012 server and was getting the "80070483" error when RDP users were trying to fax from the program. The Admin user worked fine. I read many online references that said this was a file association problem. Of course I didn't believe them. The body of my fax is coming from a text file (.txt) I create from within the program and gets deleted after the fax is sent. I removed the deletion and sure enough when I tried to open the text file I got the dialog asking me to identify which program I wanted to open it with. After I picked Notepad and tried to fax again it worked. I'm not sure what the default is on the new server, and possibly the installation of other programs deleted or altered the association. It's working now. BTW I had to make this association change for each user.

I can't imagine that 2012 would remove the default association for .txt files? (Although I don't have any accessible to check on)
Since file type associations are maintained as simple registry entries in the user hive, you could also add a quick routine in the app to ensure those keys exist (and create them if not) when it starts if this is a problem.

Thanks Jasen, I might have to resort to that. I posted this so others dealing with the same issue will try this potentially quick fix to a Faxing problem which at first inspection seems (at least for me) to have nothing to do with file associations.
