Ahh I didn't even think to check the error message.. I know why it isn't working now..

SetInfo: -2147352567 COM exception error "SetInfo" (Active Directory - General access denied error) [-2147352567/80020009]

Our AD is set up weird. We have to use this Enterprise Directory Manager tool to make any changes now. The tool is bound to an account... and the account it is bound to is the only one that has access to make changes to objects in the directory. I completely forgot about that.
