Archived - Mac OS X v10.6: Active Directory binding lost on network transition (.local domain)
If network access is interrupted, a Mac OS X v10.6 client may not be able to reconnect to an Active Directory domain whose name ends in ".local".
Lengthen the default timeout for .local name lookups by editing the following file:
The key/value pair is:
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
In some configurations, a larger timeout value such as 10 may be required. Try different values to find the one that works best.
After the file has been updated on one Mac OS X client, you can use an application such as Apple Remote Desktop to copy it to other Mac OS X clients.
