I'm upgrading CCM 4.1(3) to 5.0(4) and I'm having an issue when I use the Windows Upgrade. Everytime it gets to the part that it wants the DMA file it fails. I get a message "File Retrieval failed for unknown reason" or it states that it cannot login with the user info that I have. I've must have tried 30 different options and the same thing. I've even did an basic install to verify that everything would work, and it does. But as soon as I try the Windows upgrade it fails.
Now I've tried the 3Com FTP Server, the Pumpkin FTP Server, msftpsrvr.exe SFTP server, and no luck. Is there a better one than these that someone has had better luck with.
I've printed out the DMABackupInfo.inf file to make sure that all the setting that I put in match what's on that file. I only have the 2 servers (Pub & SUB) and one other on this LAN, the other server I'm using it has a DNS and FTP-SFTP server.
Any input before going to TAC would be very helpful. I've not had very good luck lately with TAC getting back with me.
This is the most common error message that you get with CM upgrade files. Actually, i've seen the same error on every upgrade failure and it does not give any info. You will have to connect a USB drive and collect the logs for anyone to analyse it. Though, couple of common reasons for this could be.
1. No Network Connectivity, as in Eth0 port is not disconnected.
Thanks for the reply, I do think I'm past the FTP issue and I have verified that it now does copy the file, but now it seems as if there is another issue. I did make a few backup DMA before I did the new install and tried all three of them. Now I can install the 5.x when selecting new install, it only happens when I use the DMA file. There is no firewall, it's just three PC's, the 2 CCM and a bare bones 2000 workstation with FTP on it.
Please look at my second posting and see the error it comes back with.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
