How to Create File for a Desired File Size



Posted by: Michael Khanin
Microsoft Windows

Time to time I get the need to have some temp files of varying sizes. In Linux environment it’s not a problem to do. And, in Windows environment it’s not a problem anymore :).
I’ve used a “dd for windows“. “dd for windows” could be downloded from official web site. I’ve created a very simple script, mkef.bat. Here is a syntax for using mkef.bat:

mkef.bat <filename> <size>

And now the content of mkef.bat:

@echo off
if {%1}=={} @Echo Please use the following syntax: mkef.bat filename size &goto :EOF
if {%2}=={} @Echo Please use the following syntax: mkef.bat filename size &goto :EOF
dd if=/dev/zero of=%1 bs=1024 count=%2

Windows 2003 Loses Network Connections



Posted by: Michael Khanin
Microsoft Windows, Networking

If you have a server, with Windows 2003, one day you can find your server disconnected from network :).

It’s exactly what I get. Simple reboot and server lost network connectivity.
Event log full with system errors like:

Event iD: 12291, SAM failed to start the TCP/IP or SPX/IPX listening thread

Event iD: 4292, The IPSec driver has entered Block mode. IPSec will
discard all inbound and outbound TCP/IP network traffic that is not permitted
by boot-time IPSec Policy exemptions. User Action: To restore full unsecured
TCP/IP connectivity, disable the IPSec services, and then restart the
computer. For detailed troubleshooting information, review the events in the
Security event log.

Event iD: 7023, The IPSEC Services service terminated with the following
error: The endpoint mapper database entry could not be created.

When you check MS Knowledgbase for those errors you will find the following articles, the very popular is those:

http://support.microsoft.com/kb/930220

http://support.microsoft.com/kb/912023

http://support.microsoft.com/default.aspx?scid=kb;en-us;870910

BTW, apparently it’s not caused by SP1. So, if you implemented all WORKAROUNDs mentioned in those articles, and server still disconnected from the network, try VERY simple solution :), changed RPC to start with localsystem instead of network service. Of course, remember to reboot your server :).
