Endpoint Protection

Hi I am having trouble with a client machine running XP Pro. I have deployed out clients previously and put the management console and database in the wrong place, silly me, went and removed it after setting up 50 or so users after removing just the management console I reinstall on the same server and tried to redeploy the clients to sync with the management console agian. Deployment failed, all of the clients had password protected policies, I got through that by dropping the sylink.xml in to each client folder and updating the policy. I have a single problem with one computer out of 50 and I am stumped. I tried to stop the service and couldnt even after reboot, admin rights, you name it everything. I then tried to uninstall using windows utilities add and remove programs and that froze halfway through. Great right... so I reboot and know the symantec is corrupted and I cant uninstall or repair or modify the program because it is password protected and corrupt. I have even tried to do the manual uninstall as is listed line by line here. http://service1.symantec.com/SUPPORT/ent-security.nsf/docid/2007073018014248

Is there something I am missing.
please help

if its password protected and if you not using Version 11.0.5000 you can try this workaround
Check this document

when it prompts for password dont click on ok,
open taskmanager, look for msiexec.exe
kill the one msifile which is running under logged in user account ( not the system account) the uninstall should proceed after you kill that,  

You say that you have followed the 'How to manually uninstall Symantec Endpoint Protection client from Windows 2000, XP and 2003, 32-bit Editions"

In that case try to install SEP now, when it fails go to Run type %temp% and look for SEP_inst.log
Search for return value 3 and paste 7-8 lines before that.
Even check the event viewer to see if there are any errors..?
