• free -m output, should I be concerend about this servers low memory?

  This is the output of free -m on a production database (MySQL with machine. 83MB looks pretty bad, but I assume the buffer/cache will be used instead of Swap?

• What does the red x icon mean next to a user in folder permissions (Windows 7)

  - by Scott Szretter

  In trying to debug various strange issues on a machine, I found something strange - when I go to C:\Users\administrator and get properties, security tab, it lists the users (the local admin account, system, and 'administrator' which is the domain administrator account). It all looks fine in terms of permissions (full control, etc.) compared to other machines. The one difference is there is a small red circle with an X to the left of the user icon/name. Additionally, there are various folders where it says access denied under there - for example, my documents! Even logged in as the local machine administrator account (which is not named administrator), I am unable to change the permissions - it says access denied. Any ideas what this means and how to fix it? I even tried re-joining the machine to the domain.

• Group policy doesn't let me execute Chrome

  - by George Katsanos

  Where I work, the admins just migrated us to Windows 7. They gave me admin rights but still, I had to "Run as Administrator" my Google Chrome installation. After I managed to install it, I realized I even have to go through the "Run as Administrator" shortcut every time I have to execute the application. I even edited the properties of the shortcut to check "Always run as Administrator" but nothing changed. The message I get when I'm trying to launch Chrome is "This program is blocked by group policy. For more information contact your system administrator"... Is it something I could work out alone or I have to convince them to change the "policy"?

• sharepoint 3.0 site restore/import trouble...

  - by Trondh

  Hi, We have some old sharepoint data (from a WSS 3.0 SP1 or SP2 install), that I need to restore. Problem is: This is a time management site, and one of the fields automatically pics up the user name of the user that enters data, and this is used to keep track of who worked when. Now, when I import this into my temporary sharepoint 3.0 server, these fields are blanked, and the creator of the element is replaced by my admin user (the account that ran the import job). So, to the question: Is there any way at all to grab hold of these data before the sharepoint import job "destroys" them? I'm using stsadm -o import. I don't care if I have to pick the database itself apart manually, I just need to know if it's possible to get hold of these fields with data intact from my export files... (Backup you say? It was deleted loong ago. This sharepoint export is all we have...)

• Windows 7 doesn't connect to mapped drives at start up.....

  - by danbo

  We are testing Windows 7 (32bit version) and logon to a windows 2003 domain that runs a logon script whichs maps our drive letters. We have no control over the domain. Of our 7 test users, 5 continually recieve red X's on their network drives after they logon. Double clicking on them connects the drives, however, any aplpication that requires files on the fileserver will fail since it thinks it has no connection to the drive. We have tried several reg edits (Enable Linked connections, KeepConn), we have tried to find information in the event viewer to no avail. We have also looked at any differences in NIC driver versions (none). The other 2 computers that can connect without problem are local admins, but, if we logon to the 5 that have the problem with the local admin credentials we get the red x's as well??? This one is a real head scratcher......

• Problems restoring old backups in NetBackup 6.5

  - by gharper

  I had a server that was decommissioned & replaced last year, and since the server was no longer in use, I deleted it's client & backup policy from the NetBackup Admin Console shortly afterwards. I recently got a request to restore a file from the old server, however when I specify the source client for the restore, I get an error message saying: WARNING: server (backupserver) does not contain any backups for client (oldserver) using the specified policy type (Standard) as requested by client (backupserver). [Ok] In addition to that error, I can't seem to run a Client Backup report on the old client any more to determine what tapes I need to recall in order to re-index and restore the files... My questions: Does deleting the client somehow remove NetBackups ability to ever restore files from the old system, even if the backups have a retention period of infinity? Is there a way to restore the file from the tape, assuming I can figure out which tape I need?

• Win Server 2008 R2 SP1 Repair Disk

  - by Horst Walter

  Is there nothing like "creating a repair disk" for Win Server 2008 R2 SP1. Or am I just missing it? Under Win7 I do just enter "Repair" and it finds "create a repair disk". Sorry - but I am not a professional Admin. Just using the server for my development environment. If there is no repair disk, is there something similar or something I should create in case I do have a system failure? Sure, a full backup is done, but anything else?

• Nvidia 8600 GT drivers Will not run setup

  - by Zeno

  I am attempting to upgrade my video card drivers with my nvidia 8600 gt. I downloaded the drivers from NVIDIA and when I run the setup, nothing happens. It does appear in the Processes, but never does anything. I've tried restarting, tried killing the process and re-running, I am an admin account... nothing works. What is wrong? [EDIT] The installer does run, it extracts the setup files to C:\NVIDIA as normal then when it tries to run that setup to do the actual install, nothing happens (the process does show up in Task Manager and just sits there). Attempting to run the installer manually via C:\NVIDIA\DisplayDriver\296.10\WinXP\English\Setup.exe has the process open, but nothing happens. This machine is WinXP 32bit.

• How can I re-create Microsoft Cluster Service resource groups on a different cluster?

  - by PersonalNexus

  I use Microsoft Cluster Service on a cluster of Windows Server 2003 machines containing several dozen resource groups. In the process of migrating to newer hardware, I would like move resources to the new machines on resource group at a time spread out over a few days to ease the migration and minimize risk. I was wondering of there was a smarter way to do this than manually re-creating resources on the new and then deleting them on the old cluster? The cluster has already been set up properly, the only missing is the resource groups and the resources they contain (IP, network names, services...). I have looked through the options of the cluster admin GUI and cluster.exe's commandline options, but haven't found anything like an import/export feature to copy over the configuration of a resource or entire resource group. Does something like this exist?

• telnet: Could not open connection to the host, on port 23

  - by Mihaela

  I need to telnet, to localhost. I am on windows. Once I got the error 'telnet is not recognized...' I looked online and found that I should do pkgmgr /iu:"TelnetClient". I did, then telnet localhost (0r 127.0.0.1, maybe with a port at the end), I get error: Could not open connection to the host, on port 23: Connect failed. I added the port to the firewall, disabled the firewall.. run as admin.. Please help me get telnet to work! Thank you.

• Setting the server to look for index.php file by default

  - by ????? ???????

  I am a web developer and I've requested our Sys-Admin to setup a server for my team that will be used as a development environment. The PHP is running as a CGI. When i try to open http://myaddress/ I receive 403 Forbidden. When I try to open http://myaddress/index.php everything is fine. How do I set the server to look for index.php file by default? P.S The sysadmin is not currently here, so he cannot do it for me.

• php - what kind of download counter big websites companies have?

  - by dinbrca

  Hi, I am developing in php and trying to implement a download counter to count the times that users downloaded my application.. I also read the following topics: Best way to implement a download counter? Best way to count file downloads on a website and found nothing useful enough.. What I would like to ask is: what kind of download counter the big companies implement? is it when the user cancels the download doesn't count? Is it even possible - to count file downloads, and remove 1 from the count if the user canceled the download? I already have a script that works great - but only when the file is 1MB or upper, when its less than a 1MB and a user cancels the download - the download still counts.. Thanks in advanced, Din.

• Can you have a staging and production slot in Azure Websites

  - by Barry King

  I'm looking at hosting 3 Websites (there will all use the same linked database resource but I think I have to use 3 websites within Azure for this); www.website.com, provider.website.com and admin.website.com. Using Windows Azure Websites, can you have a Staging, Production slot? I think this feature is only available to Azure Cloud Services but there is little documentation on this. If its not possible, other than spinning up 3 more sites to act as the staging sites is there another way? I want the ability to "swap" from staging to production.

• Windows Task Scheduler won't let me uncheck "Wake the computer" option for a backup task

  - by KdawgUD

  I have a problem with my windows 7 laptop automatically waking after I put it to sleep and then I find it later with the battery drained. I tracked down the culprit using the "powercfg -lastwake" command to be a Backup task in the "Windows Server" section of the task scheduler. I have tried unchecking the "Wake the computer to run this task" checkbox for this task, but after I do this and reboot, the box is always rechecked again. How can I make this setting persist? I have full admin rights to this laptop, but it is on a domain. Edit: I looked into the domain policy settings as suggested by Dave below and did not find any policies related to scheduled task settings. Any other ideas?

• IOS SDK : first advices for beginners

  - by VdesmedT

  I too often answer the same kind of questions regarding basic topics like memory management, UITableView, Interface Orientation, MVC, etc... I understand very well that everyone starting with that SDK is too exited about getting its hand on it but a few reading would save them hours of debugging and the frustration that come along with the feeling that "We miss something here". I'd like experience users to share the few small articles, white papers, docs, book chapters that helps other save their time and avoid frustration. My first vote would be for : IOS Memory Management Guide View Controller Programming Guide Table View Guide And as a General recommendation, read the Overview section that come along with every class documention in the reference library, they contains most of what you need to know to avoid big traps !

• Domain account credentials fails to start scheduled tasks

  - by neoco

  I have 2 Windows 2000 servers in a domain 'DC', which run numerous windows scheduled tasks under the 'DC\Task-User' account. These tasks are and have been running successfully in the past couple of years without any account/password modifications. Yesterday, the tasks went to 'Could not start' status. Myself having an admin account, was able to run these tasks with my credentials. Today, I ran the tasks again under the DC\Task-User account and they seem to be running fine without any issues. This has happened in the past too. I'm not into networking so don't know much about the underlying problem. Has this something to do with a Domain controller account authentication? Any pointers will be great!

• rsync assigns deny permission

  - by user773478

  Currently a script is used to copy files using rsync (version 2.6.9 protocol version 29) from Linux/Unix servers to W2K3 server using very basic command such as "rsync -v source_server::share_name/file_name /cygdrive///file_name" The script further makes copy of this downloaded file for other purposes. This is part of a larger middleware that is being moved to new hardware on W2K8R2 Second part of making copy of the file does not work using more recent rsync client version 3.0.7 protocol version 30 (shows up as cwRsync in add/remove programs) Reason being rsync assigns special permissions to file that includes deny. The user (service account) which downloads the file is in local admin group. The file can be copied elsewhere using rsync. It can be deleted. But cannot be opened or copied locally by same user as deny permission supersedes.

• Replace Certificate using Plesk 11

  - by Lambda Dusk

  I am not an admin, but a programmer. But how it is, if you're the only guy who knows about computers, everyone shoves those tasks to you. A certificate of a domain recently expired. The domains are managed using Plesk 11, on a Linux system, Apache2.2. I was given a new certificate from the host, and it is one single .pem file. However, Plesk asks me for a .crt file, a private key and some CA file. I have neither, only this single .pem file the host claims to be the certificate. Since I myself never did anything with SSL certificates, I would really appreciate if anyone can tell me what to do with this file and how to properly add a new one so the old one can be removed.

• Security Issue with Active Directory

  - by Will McCloskey

  The retard who was on the built-in Administrator login somehow (and this is what I'm guessing being as he is not here and I was not present when this occurred - Supposedly it was an "ACCIDENT") Denied the built-in Administrator account and every other account except for his personal one access to our domain - ie "Example.net" not just active directory or anything. I've been trying for literally 2 hours to find some sort of way to take control of the domain through the built-in Admin account with no success; I can't even open Active Directory. I'm not aloud to open DSA.MSC and there's no way for me to take ownership. Any ideas?
