Resolution
Lengthen the default timeout for .local name lookups by editing the following file:
/System/Library/SystemConfiguration/IPMonitor.bundle/Contents/Info.plist
The key/value pair is:
<key>mdns_timeout</key>
<integer>2</integer>
The integer value is in seconds; changing it to at least 5 should allow the Mac OS X client to reconnect to the Active Directory domain after a network interruption. In some configurations, a larger timeout value may be required.
You can change this value by using the sudo command and a text editor to edit the preference file directly. Or you can use the Terminal command below, making sure to enter it all on a single line:
sudo /usr/libexec/PlistBuddy -c 'Set :mdns_timeout 5' /System/Library/SystemConfiguration/IPMonitor.bundle/Contents/Info.plist
