<cmd_output OS="XPsp2"> E:\>set /a c = "0x54F" 1359 E:\>net helpmsg %c% An internal error occurred. </cmd_output> Isn't that helpful? ; } As usual error codes are meaningless without their context. Find where in the log that code in any of its representations is found. Then look before that. Activate verbose logging if necessary. Supplement the logging with ProcMon tracing if necessary.
