I am having a rough time with one of my DNN installs. Initially there was a enc key specified for this DNN instance. Well I needed to import some users (25,000+) and when i did this via SQL DTS the passwords in the Users table were as they were in the import table but since the portal is using an enc key those passwords are actually not the 'real' passwords. When I was able to log into this instance I tried in host settings to clear the enc key, but sadly it just killed the application and I would get time outs. The web server is a PE2650 and I am kinda bummed that I am killing it with this single task. I have looked in the tables to no avail to where this might be stored, so I thought Iwould ask you all for some pointers. It has to be saved somewhere and what I would like to do is clear the enc key and try to restart the application. Another related issue is that when I first tried to clear the enc key via host settings I crashed the server as it was trying to send out 25k smtp messages. The network guys wanted to kill me and I don't blame them. If anyone has had to deal with disabling the notification functions I would like to hear what you did for this. Right now I have just turned off smtp on the server but everytime I try to make a change via the application it wants to tell it's user base about the change. So I should have about 75k messages waiting to beat up the mail server (25k x 3 change attempts). I am scared to see what will happen once I turn back on smtp. Thanks, Ron
