After my profile became corrupt (from an IE7 developer toolbar bug... that's another story), I was forced to deleted C:\Documents And Settings[myUserAccount]. After having a sysadmin recreate the profile, I now do not have access to any of my encrypted files (using EFS Enable) - I get access denied to everything. Just speculating, and I don't really want a bunch of answers directly on this speculation, but I fear the private key was lost when the profile was deleted.
I am an admin on the machine and all the files are my own creation, and I should have full control. System restore is out of the question because it was turned off by a group policy. Looking for a way to regain access to or decrypt these files... if they are not already corrupted.
Edit: Thanks for the correction Gilles. @Randolph Potter: I have my old profile still in docs and settings as [profile]_old. Could I just delete my current on and rename [profile]_old back to [profile]? Would that by chance bring back my SID/private key? What if I set the SID of Administrator to my profile in the Registry?
