Windows annoyingly drops connections to mapped drives after 15 minutes of inactivity. Here’s how to adjust the timeouts to keep your connections alive.
Plus: New hacks may expose browser-stored passwords, more on jv16 PowerTools, and an excellent way to tame Chrome’s excessive background activity.
Mapped connections die too soon
Reader Luiz Paulo backs up his files to a mapped network drive. But Windows often drops the connection, preventing his backups from working.
- “I’ve been haunted by the red-X drive-connection warning in Windows, mainly in workgroup setups. (I’m the network administrator.)
“After some unspecified amount of time, Windows drops a mapped drive connection — possibly to free resources — and marks the drive as disconnected. I can click the drive to restore the connection, but this is a nuisance, and it interferes with a number of operations, including backups.
“The backup software can’t see the disconnected target drive. So it aborts the backup session and displays an error.
“Why does this happen? Is there a definitive solution to this problem?”
You’re correct; Windows tries to conserve resources by dropping mapped connections it considers to be idle. The default timeout is about 15 minutes.
