Does Microsoft provide a tool to help you determine the meanings of error codes?
Microsoft provides a useful command-line tool called err.exe that can help you find the meanings of error codes. When you run err.exe and specify an error code, the program searches all the error-code definitions from the various header files that Windows uses to generate a list of possible error meanings. You can download err.exe at Microsoft Web site. (Although the Web page is called “Exchange Server Error Code Look-up,” err.exe actually handles Windows OS error codes.)
You can use err.exe in several ways. Entering the command
err
with no parameters returns a list of all the header files the command checks. If you run err.exe and specify an error code–for example,
err 1645
the output looks like this:
D:tempErr>
# for decimal 1645 / hex 0×66d :
ERROR_INSTALL_REMOTE_PROHIBITED winerror.h
# The Windows Installer does not permit installation from a
# Remote Desktop Connection.
# for hex 0×1645 / decimal 5701 :
NELOG_NetlogonFailedToUpdateTrustList lmerrlog.h
SQL_5701_severity_10 sql_err
# Changed database context to ‘%.*ls’.
# 3 matches found for “1645″
