Hello All We experience some problems within our corporate network. Acronis is installed on computers and perform scheduled backup once a day. In some branch office, from 15 computers, 2 have some strange problem - during backup it failed, and the error is: Operation with partition "0-0" was terminated. Details: Write error (0x70004) Tag = 0x9D2DE1F088CBC4D4 Error writing the file. (0x40003) function = "WriteFileNoCache" Tag = 0x7CEB2CDC9FB12189 The semaphore timeout period has expired (0xFFF0) code = 80070079) Tag = 0xBD28FDBD64EDB8AF Its not network related problem, since all other computers successfully perform this task. Also NAS is not an issue by same reasons. How can we troubleshoot and fix this issue? Anyone have similar experience maybe? thx Denis.
