Analyzing server 2008 R2 dwp crash dump file

 Reading a crash dump file is far from intuitive and I spent a great deal of the morning learning about debugging. So here is what I did to read the dump file.

First, you need to install the debugging tools from here. Choose the version that corresponds to your architecture. This install will take a long time depending on your network speed. Important is that you include the WinDbg.exe because that is the tool we will be using.

Next, you need to download the symbol files. Note that you can also use the symbol server from Microsoft but it is faster to have a copy of the symbol files on your hard drive. Download them here. Just download them all. And this will also take a long time because the Symbol files are huge.
Next! Open C:\Program Files\Debugging Tools for Windows (x86)\WinDb.exe.

Choose File -> Open -> Symbol File Path

Type: SRV*C:\Symbols* like this:

Now press CTRL+D to open the DWP file! Very exciting.

Now, if you enter !analyze -v like this:

And you’ll get more information about the crash. In my case:

* Bugcheck Analysis *
* *

One or more critical user mode components failed to satisfy a health check.
Hardware mechanisms such as watchdog timers can detect that basic kernel
services are not executing. However, resource starvation issues, including
memory leaks, lock contention, and scheduling priority misconfiguration,
may block critical user mode components without blocking DPCs or
draining the nonpaged pool.
Kernel components can extend watchdog timer functionality to user mode
by periodically monitoring critical applications. This bugcheck indicates
that a user mode health check failed in a manner such that graceful
shutdown is unlikely to succeed. It restores critical services by
rebooting and/or allowing application failover to other servers.
Arg1: fffffa8038f3ab30, Process that failed to satisfy a health check within the
configured timeout
Arg2: 00000000000004b0, Health monitoring timeout (seconds)
Arg3: 0000000000000000
Arg4: 0000000000000000

3 things has to be done for better performance

  Tips from Goutham: 3 things has to be done for better performance: By default, XP displays extra graphic objects for menu items which can slow down your display. 1. To turn off these selectively... Right click My Computer Select Properties Click Advanced tab Under Performance, click Settings button To turn them all off, select Adjust for best performance Preference is to leave them all off except for Show shadows under mouse pointer and Show window contents while dragging 2. To speed up the display of the Start Menu Items, turn off the menu shadow. Right click open area of the Desktop Select Properties Click Appearance tab Click Effects button Uncheck Show shadows under menus 3. You can increase system performance by loading more of the system into memory. DO NOT attempt this with less then 512MBs of ram. Your system will become unstable. Click Start Click Run Enter regedit Click OK Go to HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Session Manager Memory Management Double cli

The difference between DNS and NDS

  Novell Directory Services(NDS) - Novell Directory Services (NDS) is a popular software product for managing access to computer resources and keeping track of the users of a  network , such as a company's  intranet , from a single point of administration. Using NDS, a network administrator can set up and control a  database  of users and manage them using a  directory  with an easy-to-use graphical user interface ( GUI ). Users of computers at remote locations can be added, updated, and managed centrally. Applications can be distributed electronically and maintained centrally. NDS can be installed to run under  Windows NT , Sun Microsystem's Solaris, and IBM's  OS/390  as well as under Novell's own  NetWare  so that it can be used to control a multi-platform network. NDS is generally considered an industry  benchmark  against which other products, such as Microsoft's Active Directory, must compete. Lucent Technologies plans to integrate NDS into its own QIP product
