Semaphore Timeout Error occurs when copying large files

Question

I am getting a Robocopy error message moving from my Local drive across to a Nas server share on a gigabit network connection.

2022/05/29 21:31:37 ERROR 121 (0x00000079) Scanning Destination Directory z:\mail\
The semaphore timeout period has expired.

So this does not seem to have a fix in windows 10 going back to Windows XP???

Hi ChrisOwen-5066,

This issue is normally caused by a network speed issue, your antivirus or disk integrity. You should check your network drivers, temporarily disable your antivirus and perform a disk check.

I hope this answers your question.
