I have a Mac Mini (HTPC running 10.8.5) and a Mac Pro (primary computer running 10.9.2). Just yesterday, my Mac Pro can no longer connect to the the Mac Mini... I get the attached error message. It says to contact my system administrator... which is you guys I can connect via screen sharing to the Mac Mini no problem... just not the drives (file system). The Mac Mini can connect to the Mac Pro without problem. Both computers can connect to the Time Capsule drive without issue. Both computers have a DHCP IP address reservation. File Sharing is enabled for the Mac Mini of course (that hasn't been changed). Strange days. Any suggestions on what might have changed to cause this or what to try to get file sharing working again from the Mac Pro to the Mac Mini?
