Good posting Fred, your steps are correct on the install, just a few additions.
1) On the Add/Remove - choose you latest Full package.
2) It will prompt you to install a Development or Production install. For a metaframe you will want a Production install. It is best to install this on an apps drive, not your C:\.
3) For 2003, you will want to give annonymous or guest (however you Citrix signs on the users to the publish app) access to the drive that has PeopleSoft installed on it, plus the security files on C:\ jdeauth* & jdesec*. Since 2003 installs with everything locked down.
4) Note that (at least in E810), your users will get that annonying pop-up for tip-of-the-day. This is because the customizations that your citrix users do is made in the registry for how they signon. So if you publish OW for anonymous users, then their registry changes will be deleted when they signoff and the next users adopts their logon (to the server, not into OW). Annoying but easy.
If you publish OW for explicit sigons, then all your users will have a profile (in /documents and settings/) and it will save their customizations (tip-of-the-day, address bar location, size.... all that apply to save-on-exit). Nice for the users, but terrible to maintain.
5) You do have to run the R92TAM & R98CRTGL, but these have to be run on a local box - normally this override is not done on a metaframe. It's done on a local workstation, the files are stored on the deployment server, and then copied down to each MFrame.
This needs to be done, since JITI'ing is not good on a MFrame, (if it is even allowed to in the first place).
As for publishing - that's your call. Just keep in mind that a OW user takes about 100Mb of Memory (very little CPU) and they will sit in there all day if they could - so I would set a resonable timeout.
Remember to cleanup the PRINTQUEUE directories often (ever PDF they view is pulled onto the MFrame from the ES).
The extras (printing and mapping drives) are joys that you will discover as they ask for it.
Good luck,
Kristian
