Domain Controller Diagnostics Tool (dcdiag.exe)

Applies To: Windows Server 2003 with SP1

What does DCDiag.exe do?

This command-line tool analyzes the state of one or all domain controllers in a forest and reports any problems to assist in troubleshooting. DCDiag.exe consists of a variety of tests that can be run individually or as part of a suite to verify domain controller health.

Tool Requirements

• Except as noted below, all commands in DCDiag can be run on Windows XP Professional and Windows Server 2003 family (member servers and domain controllers).

Objective
Bond two DS1s (T1s) together for 3Mb bandwidth. 2 VLANs that need to certain access to other subnet’s resources such as printing.

Layout
Carrier: Level 3
Router at Customer Site:

This is what I have for a router config. It has been working 3 months no issues. I took out the ACLs for this output. (Still on the router but not here)

For some time I have created ACL Standard or Extended. Then six months to a year later after creating the ACL the customer wants me to update or check to see what this does and when was the ACL applied. Named ACL really help. I know the date and how many changes in the date I update the Named ACL. Please use a text editor for all changes. Cisco recommends this.

Example:

ip access-list extended Ban_Sept_25-2007e
deny ip host 64.235.213.22 any
deny ip host 207.138.82.130 any
deny ip host 209.170.119.67 any
deny ip host 64.116.204.140 any
deny ip host 63.211.225.83 any
deny ip 8.6.12.0 0.0.0.255 any
deny ip 64.74.0.0 0.0.255.255 any
permit ip any any

Copy IOS for Flash card to Flash Card.

copy slot0: slot1:

cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc
cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc
cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc

This works great, howerver, if you type delete xxx file it will not clear the blocks on the card.  I had to format (format slot1:) in order for me to copy the IOS on to the card.  When I type delete it would not free up space on the card.

I use kermit with a USB serial to USB cable.

kermit

set line /dev/ttyUSB0

set speed 9600

set stop-bits 1

set parity none

set flow control none

set carrier-watch off

connect

Same for windows Hyperterminal.

rommon 1> confreg 0×2142 (make sure your router has this)

rommon 2> reset

then once the router reboots then a setup will occur.

Steps from start to finish:
1) Make sure all IOSs are the same.
To copy an image From switch:
“copy image.bin tftp:
Address or remote host name[ip address or hostname]10.0.0.40
Destination file name [xx.bin]what you want to call the file
then you will see
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! til it is done
To copy an image to a switch
“copy tftp:junk junk (works this way for me)
Address or remote host:[10.0.0.40] enter IP
Source filename:[me.bin]flash:c2950-i6q4l2-mz.121-13.EA1.bin
Access tftp://10.0.0.40/me.bin
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! until it is done

Using the current technologies with VMWare, Windows, and Cisco, it is possible to have a live backup at an alternate location. The link below show a demo Viso layout of Windows 2003 Doman Controllers and SQL running a cutomers location and being repicated over a T1 to a hosting company. This aritcle will be update from time to time to get results of T1 usage and how VMWare performs.
