I installed a Forwarding DNS server on Centos 5.10 and it is resolving addresses e.g google.com. When I stopped named (service named stop) and tried to dig (dig @localhost A google.com) there was a failure to resolve the address. I checked and see the caching daemon nscd is running.
Does this mean the server is not caching at all? How can I get it to cache?

Ok, this is my first time with windows server os. I started doing this out of curiosity.
I have a desktop running windows server os 2003 which is connected to a wifi router. I have a laptop that connects to this router wirelessly and THIS REPRESENTS A REMOTE USER.
I want to provide access to this user to a set of files ON THE SERVER.
So i create an account for this user, as
Start - programs - admin tools -user manager and then the steps to create an account.
When i use this laptop, i log in as administrator as its the default account that came. Now when i want this laptop to be the user i just created on the server, HOW DO I DO THAT?
I'm testing MFCMapi and the Exchange CDO 1.2.1 on a Windows Server 2008 R2 PC and I continually get a
Err: 0x8004010F=MAPI_E_NOT_FOUND
Am I correct in assuming that the Exchange CDO pack does not work properly on 2008 R2?
I have a very special case that I have been working on for several days. I have a very large SQL Server 2008 database (about 2 TB) that contains 500 filegroups to support very large partitioned tables. Recently we had a catastophic failure on one of the drive and lost several filegroups and the database became in-accessible.
We have been doing filegroup backups on a daily basis, but due to other issues, we lost our most recent backup of the log and the primary filegroup. We have all the data backed up but the primary filegroup backup is old.
There have been no schema changes since the primary filegroup backup, but the lsn's are now all out of sync and we cannot recover the data.
I have tried everything I could think of (and have tried just about every trick and hack I could google) but I still end up at the same point where I get messages saying that the files for filegroup x do not match the primary filegroup. I am now at the point of trying to edit the system tables (we have a separate temporary environment to do this so we are not worried about corrupting any production databases). I have tried updated sys.sysdbreg, sys.sysbrickfiles, and sys.sysprufiles to try to trick SQL into thinking all the files are online, but a "Select * From OPENROWSET(TABLE DBPROP, 5)" shows a different database state from what I see in sys.sysdbreg.
I am now thinking I need to somehow edit the headers of the actual data files to try to line up the lsn's with the primary.
I appreciate any help anyone can give me here, but please do not respond with things like "you are not supposed to do edit mdf, ndf files...." or "see msdn article....", etc. This is an advanced emergency case and I need a real hack so we can just get to the data in this corrupt database and export to a fresh new database. I know there is a way to do this, but not knowing what the DBPROP system functions does (i.e. does it look at system tables or does it actually open the file) is keeping me from trying to figure out how to fool SQL into allowing me to read these files.
Thanks for any help.
I have a Ubuntu-server. I am trying to install Vsftpd but it shows the :
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package vsftpd
After that I checked internet connection by ping 4.2.2.4 and there was no problem in internet connection.
I tried to apt-get update but it was not possible it shows:

We are planning to upgrade our hardware and at the same time we plan to reinstall all our web server from a fresh OS.
Currently our web server is running on CentOS 4.7 on a dedicated server. We are using Apache, Mysql, PHP, SVN, FTP and all the needed tools for a web server managed through SSH.
We plan to use a cloud server for the new web server. I don't know which Linux distro to take for this new server. Should I stay with Centos and just take the latest release 5.4 or should I switch to something else like a Debian base distro (Ubuntu Server)?
The thing that I didn't like with CentOS was the none availability of the latest version of PHP and Apache on Yum. This make it harder to keep our webserver updated with the latest technologies...
Thanks for your help!
Hi,
Im relatively new to Ubuntu, Im wondering how easy it is to write what I think is called a shell script to make tasks a little easier.
For example I frequently connect to a server - ssh -p 123 [email protected]
Can and how could I shorten this to a shorter command like "mysite" or "connect mysite"
Thanks.

I want to use Windows Server 2008 R2 as a host, and load RedHat as a guest OS.
Should I use VMWare, or does Windows have something built in that competes with VMWare?
I was wondering if anyone have experience with building server rooms in shipping containers, how viable it is, and what to look out for.
We need more space, but can't build due to restrictions, so we are wondering about placing down some permanent containers to house servers, i know it has been done before, but i was wondering if anyone has any experience with this.
Could help me out a lot in upcoming meetings with building companies!
Thanks!

Is that possible to organize nightly builds at Ubuntu Server using MSVC++ compiler?
I mean is it possible to install Visual Studio 2008 and run msbuild.exe in Wine by scheduler to compile C++ solutions?
EDIT: I have used VirtualBox with Win7 in in. It works fine.
I'm currently using HP Proliant DL120 G5 servers running VMWare ESXi 4 to run server VM's. They are connecting to an iSCSI SAN for the shared storage. I'd like to implement a delayed boot of these hosts servers so that they don't boot up and try to connect to the SAN before the SAN is ready for connections after a power failure. Does anyone know of a good way to do this?
I'm troubleshooting a Polycom SoundPoint IP 550. I have wiped the hard disk of the phone (via a menu option) and now it's stuck in a reboot cycle. Apparently the only way to setup the firmware of the phone is to use a boot server.
Does anyone know another way to setup the phone/firmware?
One of our developers worked on a beta server and accidentally changed the permissions of the whole system (chmod /) to root. Due to that, services are unable to access files, and we can't ssh to the machine (permission denied on the key) (UPDATE: ssh is dead after reboot, probably can't start).
Does Amazon has an option to browse files / physically access the machine?
Any other creative solution?
File sharing on Windows XP has a 5 client limitation. Our solution uses both file sharing and SQL Express.
The way I see it, we have 2 options here:
-Reload the machine that they want to use as a server with Windows Server, or;
-Supply them with a dedicated NAS server, and keep their server machine on Windows XP
The second option is the preferred one, for reasons I'm not going to go into. I just need to confirm that the 5 client limitation applies to the file sharing only.
I have proxy server that sits in the DMZ. The default site is running the adfs and has a certificate that is about to expire in 2 weeks. I am not sure what are steps involved in applying a new ssl certificate. I know at the least I will install the new certificate(s) in the local store. Go to IIS and change the certificate using the binding settings. Is there any othern place I have update the certificate?
I've got an old linux server that failed to boot this morning. It's running Debian stable. I get the following on the console:
LILO 22.8 Loading Linux......................................................................................................................................................... ............
And it just sits there. Any idea what is going on or how I can fix this?
I've installed Ubuntu 12.04.1 in a new server and set up the 4 hard drives with 3 RAID 1 devices, the configuration is such that the first two drives have md0 (swap space) and md1 (/) with the third and fourth drives having md2 (/var).
I've been testing the operation under a drive failure and found that the system boots fine if I remove disk two but if I remove disk one then the system gets to grub and then just restarts. I'm confused as to why grub appears to be loading properly from disk two but then the boot fails.

I'm having a frustrating problem with browsers on OS windows 7 home premium.
IE 10: My web browsing works ok for a while and then pages freeze and tab at top says "Waiting for ...' and never loads. Strangely I can still get to Google search results but if I click anything it freezes.
Chrome freezes too and says 'The page has become unresponsive ...kill page'
Safari stops also.
I have tried clearing cookies, cache, turning off Bitdefender firewall and nothing apart from a restart fixes it. consequently I am forced to restart my computer several times a day to stop this browser hang. I have no idea what could be causing this ..any help greatly appreciated.
Hello Experts,
if I want to querey the DNS delegation "manually", I normally start using one of the "DNS-Root-Servers", like b.root-servers.net.
dig @b.root-servers.net test.com
But what if the root servers would change? My question is, is there any possibility to query a "central Server" even being "above" the root servers that returns me the list of Root servers?
When i upload my rails app via SFTP to production server which is running Ubuntu 10.04 LTS all cyrillic characters in my files look like this:
http://dl.dropbox.com/u/347209/chars.png
As you can see, only parts of words are broken. And because of this rails app doesn't start with syntax error.
Also i'm getting errors like
ActionView::Template::Error (incompatible character encodings: ASCII-8BIT and UTF-8)
