3 Windows Server 2003 domain controllers and exchange server was not properly shutdown

Good morning, we got three domain controllers and one exchange running on Windows Server 2003, yesterday there was a power outage for x number of hours, all of them are plugged into UPS, but it could olny hold power for 45 minutes. And I was not able to properly shut down each servers. now, every servers are powered on by itself. I did not do anything yet but to log in to each servers and they are working, what potential risks/damages might have happened during the power outage/improper shutdowns? Also we got Red Hat Linux 10 server that was not properly shutdown,. What should I do? Thanks a lot. How am I gonna know when the power came back up? thorugh event logs?

I would type

dcdiag /s:server1 /e

Note the spaces. server1 being your PDC or FIRST DC in the network.  If you run a dcdiag /? you can get all the parameters including one to save to a file you can print out and study.

Every Windows server that shut off due to power failure will have an event in the event logs stating the server was shutdown for an unknown reason.  That will show the time the server came back on.

Just run server diagnostics: dcdiag, netdiag, repadmin.  Also peruse the event logs.  Make sure DNS is working.  Thatls all I would do unless I do get an error and then troubleshoot the error. Remember you will see error messages after the initial turn on as the servers re-establish communication.  Be patient and wait a few hours, the event log errors should all go away.

DNS servre.  Go to Administrative Tools\DNS

If the DNS server is down then the server will have a small red icon, working is green.

Better yet

run dcdiag /dns dnsall /e

this will run dns diagmostics in verbose mode for all dns servers in the enterprise.  The reason is really for you for referance, there is no requirement or need to be accurate otherwise.  You can type a single character in the commnet section.

this happends all the time and I've never had any issue with a windows server not being cleanly shut down.  the only thing that really risks corruption are any third party databases you might have on the servers.  Simply powering the servers back up will get them going again.

>>Also we got Red Hat Linux 10 server that was not properly shutdown,. What should I do?
this is a windows 2003 topic area,,, i suggest you post any Linux questions in the Linux topic area.

thanks for the reply, is it okay to run diagnostics while the servers are in production?

mikeleebrlaCommented:
yes, they will not affect anything except slow down performance a little.  Probably not enough to even notice, depending on your hardware.

I do all the time

You can also download the tools onto a XP, SP2 administrative machine.  You then add the parameter for the server to run against in dcdiag.  for ex, if the server is SVR1, then:

dcdiag /s:SVR1 /test:dns /e

will run against SVR1, just the DNS test and the /e runs the tests on all dns servers.

dcdiag /s:SVR1 /e /v

runs all major dcdiag tests, against the enterprise and with verbose output.

addoing /f:filename   gets you a file output to print and read...  Try the dcdiag /?  for a complete list.

If you run dcdiag on a server then you don't need the /s switch

run repadmin /showreps on the PDC for a nice display of AD status

or Google:

download Windows Server 2003 Service Pack 1 32-bit Support Tools

There are many useful tools in this download.

I recommend running dcdiag at least weekly.

I think we already got this on Windows XP, is it the Administrative tools?

toptop777Author Commented:
I got that installed on my Windows XP but I cannot find where to run dcdiag. Thanks

d50041Commented:
You have to run it from the directory it is installed in: C:\Program Files\Support Tools

If it is not there you have a different set of tools.

it is for Windows Xp or Windows Server 2003 I got one installed under program files on windows XP, administrative tools whish has Performance, Active Directory and Trusts, Computer Management, DHCp, etc.

d50041Commented:
that is a confusing response, sorry.

The tools run on XP or Server 2003.

That is different than the Administrative tools you listed.

Did you download and install the tools?  If yes then you should have the directory previously specified. The Administrative tools download is an optional add-in.

Athe adminsitrative Tools on Windows XP was installed by our IT consultant so I would be able to do administrative tools from Windows XP. What should I do next?

d50041Commented:
Use Windows explorer search feature to find the dcdiag.exe utility.  It should be installed in the C:\Program Files\Support Tools folder.  If not, then download and install the Administrative tools file from Microsoft.

How come if I run dcdiag/s: companyzeal, it gives me the results but if I run dcdiag/s:companyzeal/e/v, it says

Domain Controller Diagnosis

Performing intial setup:
[companyzeal/e/v] LDAP search failed with error 58,
The specified cannot perform the requested operation..
The host companyzeal/e/v could not be resolved to an
IP address. Check the DNS server, DHCP, servername, etc.

Thank you very much.

does Windows Server Support Tools need to be installed on all three domain controllers servers?
0
 
d50041Commented:
no, it does not "need" to be installed on any server or just on one.  You can install the support tools on an XP workstation.  Use the paramter /s:servername after dcdiag to point to the server you are running againt, even if you use /e, which runs ahainat all servers in the enterprise. If you install on a DC than you don't need the /s:servername as dcdiag will default to the server it is on.
