Remote Management - can't add Admin user account
I have just imaged my iMac lab to Lion. I am using Apple Remote Desktop 3.5. (I have used it for several years and know how to set it up and use it.) The problem I am having is adding my admin account to the list of users that are allowed remote management through sharing in system preferences.
The user list shows every other account, but will not show my admin account. I have image labs each year and have never experienced this issue. Not sure where to go from here.
iMac, Mac OS X (10.7.4), ARD 3.5.2
