Rebooting server causes PC to lose connection

[Guest Net Admin]

I have 2 Domain Controllers at my site. Both are Global Catalog Servers, DNS

servers, WINS servers, and are version 2003 Standard with SP2.

When I reboot either one, some of my servers report errors about not bieng

able to connect to other servers in my domain such as the database server. In

the IP properties of each member server I have both DNS server IPs entered.

Is there a timeout period that has to occur before the member server

switches over to another DC to authenticate or resolve names? If so, how to I

speed that process up?

Thank You

[Guest Meinolf Weber]

Re: Rebooting server causes PC to lose connection

 

Hello Net,

 

Please post the complete error from the event viewer. Some entries if they

only show up after restart can be ignored. But we have to see the complete

errors for this.

 

Best regards

Re: Rebooting server causes PC to lose connection

 

Here is the error from a Sharepoint web server:

 

#50070: Unable to connect to the database dbpublic on db1.mydomain.net.

Check the database connection information and make sure that the database

server is running.

 

That error will occur until the DC comes back up even though the other DC is

up and running just fine. db1 is up the whole time.

Re: Rebooting server causes PC to lose connection

 

Hello Net,

 

Is db1.mydomain.net the sharepoint server or an additional? Did you run netdiag

on the sharepoint machine and how is your DNS setup? Seems that during the

reboot the machine lost the connection to the DNS server.

 

Best regards

Re: Rebooting server causes PC to lose connection

 

Db1 holds the SQL database. The Sharepoint Web Server is where I get the

error whenever either of the DCs reboot. I ran netdiag and all tests came

back with "Passed". I did find this to be odd though:

 

"Trust relationship test. . . . . . : Passed

Secure channel for domain 'CORP' is to '\\DC1.mydomain.com'.

Cannot test secure channel to other DCs since you are not an

administrator."

 

I am an Enterprise Admin. I am a member of Admins on that server.

All servers at this site use one of the DCs as their first DNS/WINS server

and the other as their secondary. It does sound like during the reboot the

Sharepoint Web Server lost connection to the DNS server but shouldn't it have

swithed to its secondary DNS server immediately?

Thanks for helping, Meinolf.

Re: Rebooting server causes PC to lose connection

 

Hello Net,

 

It will not switch immediately to the other DNS, it only will switch, if

the server makes again a request and then will realize that the preferred

DNS server is not available.

Re: Rebooting server causes PC to lose connection

 

That's what I thought but that error continues for about 4 minutes until the

server comes back up (87 errors total). It should have switched after the

first few errors shouldn't it have?

Re: Rebooting server causes PC to lose connection

 

Hello Net,

 

Good question, but i am not a DNS expert for this details. I would think

the same like you, but maybe the connection to the database does not completely

needs DNS during work. Except from the Sharepoint error, are there anything

else in the event viewer in this timeframe?

 

With dnslint you can also check DNS name resolution issues.

http://support.microsoft.com/kb/321045

 

Have you also checked the DC/DNS servers with dcdiag and netdiag for errors,

just to be sure that there is no additional problem? And do you use Active

directory integrated zones?

 

Best regards

Re: Rebooting server causes PC to lose connection

 

No, no other errors whatsoever. I did check all DCs for DNS errors some time

back. Maybe I should do it again.

I had forgotten about DNSLint

Thank You Meinolf, I will run tests and respond with the results tomorrow.
