Microsoft says it will roll out a fix for the mapped network drive bug in Windows 10 version 1809 (October 2018 Update) by early December 2018.

The company acknowledged the bug earlier this month, but it promised a fix sometime in 2019. The advisory page providing details on Windows 10 version 1809 bugs was then updated to indicate that the fix could actually land by late November, while the most recent update points to a potential release date in December 2018.

This means the very next cumulative update for Windows 10 version 1809 could include this fix, or Microsoft may wait until the December 2018 Patch Tuesday to resolve the problem. Patch Tuesday takes place on December 11.

Microsoft is already testing Windows 10 cumulative update KB4469342 for version 1809, but a fix for the mapped network drive bug wasn’t included, according to the official changelog. It’s not yet clear if a solution is available internally or not.

“Known issue”

According to Microsoft, the issue causes mapped drives to fail to reconnect after starting and logging to a Windows device. There are three symptoms of the bug, as it follows:  

· In File Explorer, a red "X" appears on the mapped network drives.
· Mapped network drives show as "Unavailable" when you run the net use command from a command prompt.
· In the notification area, a notification displays, "Could not reconnect all network drives."
  At this point, a workaround does exist, and users need to set up scripts to automatically reconnect a mapped network drive. However, the full fix coming in early December should resolve the problem completely.

Windows 10 version 1809 was re-released earlier this month after previously being pulled in October due to critical bugs causing data loss. The company has also acknowledged several other bugs in this second version of the update, and the next cumulative update could address at least some of them.
