Question : Citrix PNagent Pass-through Authentication Change & Re-Install Problem!

I have been using PNagent with prompting user credentials on a MetaFrame XPa farm for several years.

However, now we are moving to a Presentation Sever 4.5 farm and set the web-interface PNagent site to only accept Pass-through authentication and I have the following issues/questions:

[ISSUES]:
1.) After updating URL to new farm, properties of PNagent | Logon Mode reverts to blank and pass-through option does not take/save.

2) A reinstall of a custom packaged Citrix PNagent w/ new URL and local credentials enabled still prompts for login

3.) It seems only a manual full Uninstall of PNagent 8 and a reinstall works for Pass-through

[QUESTIONS]:
A.) How can I update the existing PNagent installation to migrate from Prompting to Pass-through of authentication without a manual uninstall/reinstall?

b.) Is there a way to script and/or silently uninstall the Citrix PNagent 8.0 using software deployment (i.e. SMS, DesktopAuthority, KACE)?

* I have exhausted myself and had NO luck with the below tips for automated silent method of uninstalling the PNagent 8.0 :

- MsiExec.exe /I{D8A8C84C-8095-4DF3-8C3D-38DD0772E00B}
- DesktopAuthority software deployment uninstall element
- Manual modify registry by injecting 'pnsson.dll' references
- Manually modify registry by verifying URL
- Verified domain name cache is accurate and domains exist

HELP WOULD BE GREATLY APPRECIATED!

Answer : Citrix PNagent Pass-through Authentication Change & Re-Install Problem!

How about something like: MsiExec.exe /x{2C42ED1E-6315-4E63-89E6-057EA114EBB8} /qb-!
Here's another one to try: msiexec.exe /x {2C42ED1E-6315-4E63-89E6-057EA114EBB8} /q /L"V*"c:\ica32remlog.txt

Looks like the main difference between what you got and the strings i found with google is the /x instead of /i....
