I finally moved all of the computers over following about a month of testing. Everything has been working smootly. I like it much better than version 2. However, I had to completely start from scratch as my wsus v2 was on 2k servers and v3 is only supported on 2k3. I also like the approval rulesets you can create.

Are you encrypting the communications using ssl? I am for the domain members... but I think I'm going to have to leave the boxes that are not domain members unencrypted because I can't push out the certs. I'm encrypting between replica servers but I'm going to have to leave off the ssl requirement for one of the servers... Not that it really matters... I'm on a private LAN and it's not going over the internet or anything.
