Few days ago I need test the stability and throughput of the network between two servers in our organization. I have tested several free tools but the most interesting tool for me was NETIO Benchmark. It’s small tool which is working on client/server technology, allow easy and fast check of the network throughput via NetBIOS, TCP and UDP protocols (using various different packet sizes).

Solution:

  • Download & decompress the NETIO Benchmark tool
  • Execute Win32-exe file on the server side with parameters: “-s -t -u”
  • Execute Win32-exe file on the client side with parameters:
    • for TCP test “-t {server_IP}”
    • for UDP test “-u {server_IP}”

Posted by MLK under Windows Events

Description/Problem:
Some weeks ago I had an issue related to non-administrator users which were not able to logon over graphical user interface into the Windows Server 2003. This server was operated as domain controller with basic security settings.

Solution:

  • Set correct files system permissions to folder “%systemroot%\WinSxS” and all sub-folders
    BUILTIN\Administrators:(OI)(CI)F
    NT AUTHORITY\Authenticated Users:(OI)(CI)R
    CREATOR OWNER:(OI)(CI)(IO)F
    BUILTIN\Server Operators:(OI)(CI)R
    NT AUTHORITY\SYSTEM:(OI)(CI)F
  • Set correct files system permissions to folder “%systemroot%\AppPatch” and all sub-folders
    BUILTIN\Administrators:(OI)(CI)F
    NT AUTHORITY\Authenticated Users:(OI)(CI)R
    CREATOR OWNER:(OI)(CI)(IO)F
    BUILTIN\Server Operators:(OI)(CI)R
    NT AUTHORITY\SYSTEM:(OI)(CI)F

You can use tool called Extended Change Access Control List (Xcacls) to easy setup of specific file system permissions for files or folders.
