We have several MAC's on a Windows domain, along with PC's. One user account (Fred) is unable to access SMB shares on a Windows server from one of the MAC's. His account can access the same shares from other MAC's and other Windows PC's. Other users can use this problematic MAC and access the same shares just fine. It appears to only be Fred's account while on this one MAC that is unable to access the SMB share. Is there some way to wipe Fred's profile from the MAC or keychain or something along those lines?
