This is our setup:
All computers resides in a normal "productiongroup" in SEPM, and when a client needs SEP uninstalled, our Antivirusdept. moves the client to an Uninstallgroup which makes it possible to uninstall SEP using Cleanwipe and a given password that I have.
If a computer is not moved to this Uninstallgroup, that password will not work. (I once ended up with teeferdriver corrupt because Cleanwipe messed up when not getting correct pw, but I'll leave that for now...)
Now, when this computer has been moved to another part of our company, and does not have a LAN connection we forgot to have the computer moved to the Uninstallgroup.
Our Antivirusdept. gave me a possible unsupported solution to trick the client into uninstallgroup by replacing sylink.xml, but the GUI never seems to pick this up.
